Turnkey Instruments Australia
Real-Time Dust and particulate monitors
We offer a range of dust and particulate monitoring equipment. All our scientific testing instruments are designed and developed in-house by our team of specialist engineers.
We currently supply our dust and particulate monitors to clients of all shapes and sizes all around the world for use in a range of settings. They are routinely used on industrial sites, in manufacturing plants and by local authorities, councils and those involved in scientific research in this field.
Our iPM and Osiris monitors are Environment Agency MCERTS certified. In addition to measuring airborne particles, they can also be used to measure environmental factors such as
- wind speed and direction
- temperature
- humidity
- rainfall
All Turnkey’s dust monitors are compatible with the AlarmBox which can be set up to provide audio or visual alarms of predetermined levels of pollutants are reached or exceeded. iPMplus and Osiris can also be used alongside our iGAS gas monitor and our noise and vibration monitors at the same site and can be optionally powered with our solar and mobile solar solutions.

iPM Plus
Turnkey’s new iPM instrument employs a unique combination of light extinction and light scatter to accurately analyse individual airborne particles. This allows the instrument to simultaneously measure all the PM size fractions with great accuracy.
Unlike fan-based samplers, iPM has a proper pump, air filter, and accurate flow controller to generate a stable sample airflow. It also generates recirculated clean air to keep its optics away from dust and dirt contamination. Its proprietary long-life pump uses an ultrasonic mechanism and is virtually noiseless. The filter capsule is interchangeable and can be sent for material analysis of the collected dust.
To remove water droplets when sampling in damp or misty conditions, the iPM has a temperature-controlled heated inlet. The user can adjust the sample temperature set point. Or, if an ambient T & RH probe is fitted, the sample flow can be held at constant humidity.
The iPM is MCERTS approved for PM2.5 and PM10 measurements.

Introducing Turnkey’s iGASpod.
Add gas pollutant monitoring to your iPM dust monitor with the new iGASpod.
Just plug into your iPM to measure up to four gas species at levels down to ppb concentrations.
Gases include NO2, NO, O3, CO and volatile organic compounds (VOC).
Proprietary electronics and software algorithms give exceptional stability of readings with resolution down to 0.1 ppb, and species cross-sensitivity corrected for. Built-in battery keeps the sensors powered so they are ready to record at any time.
There’s never been an easier way to measure dust and gas pollution all in one package. See more information on the iGASpod.
Osiris
Our Osiris air monitoring device measures airborne particles. The Osiris combines versatility with accuracy and is suitable for use in a wide range of locations and scenarios.
It can be used for short- and long-term studies, simultaneously measuring TSP, PM10, PM2.5 and PM1 particles with a resolution of 0.1 µg/m3. In workplace mode, it will indicate inhalable, thoracic and respirable concentrations.
The Osiris can be used as a portable instrument or deployed in a permanent installation, making it the ideal monitor for studying short- or long-term pollution hotspots in towns and cities, and on sites where airborne particles could be a concern and require monitoring.
It can be housed in an environmental cabinet, and in addition mains power the Osiris also offers the option of powering by a solar semi-mobile or fully mobile setup.
The Osiris has been Environment Agency MCERTS certified so users are guaranteed reliable and accurate recording of PM10 and PM2.5 data.
How it works
The Osiris, along with our other airborne particle monitors, works using Turnkey’s specially-developed nephelometer. Air samples are continuously drawn through the nephelometer, which analyses individual particles as they pass through a laser beam. The particles are then collected on the reference filter. The nephelometer’s microprocessor has the capacity to analyse individual particles, even if there are millions of particles per litre.
Reporting and analysing data
The Osiris works with our specially-developed AirQ software. This enables results stored in the Osiris memory to be uploaded to your PC. With AirQ, you can also use your computer to control the Osiris and collect results in real-time.
Data and results can then be easily reported and collated using AirQ. Graphs and tables can be exported to Excel for further analysis and reporting purposes.
When used with a Turnkey PowerPortal the Osiris may be used with our AirQWeb online interface. Data is collected from the instrument, and AirQWeb provides a free, user-friendly platform for accessing, reviewing, and storing your data. It enables users to generate graphs and reports, which can be converted to Excel or PDF documents for further reporting and analysis.
Additionally, we have developed the AirQApp for Android and Apple mobile devices, enabling users to access data on the go. With the app, users can generate 3D graphs, start and stop sampling, change the configuration of the sensors, and generate reports.
Additional monitoring
The Osiris can also measure wind speed and direction, temperature, humidity and rainfall or a range of other external sensors. It can also be used off-grid where there is no power at the site, with our solar set-ups.

iGAS
iGAS is our internet gas monitor, measuring 6 different gas species simultaneously.
Our gas monitors allow easy recording and reporting of multiple gas species, viewed remotely through AirQWeb.
Like particulates, pollutant gases significantly affect the quality of air we breathe. They are often present in the same environments and generated by the same sources, such as industry and road traffic.
We have recently developed gas monitoring instruments to complement our range of dust monitors. The iGASair can measure up to six different pollutant species simultaneously, with all data stored and displayed on AirQWeb, alongside data for any dust or noise & vibration instruments. It can also be used remotely without site infrastructure by utilising our solar-powered and mobile setup options.
The monitors use a variety of methods, such as electrochemical cells, nondispersive infrared sensors, and photoionization detectors to measure different gas species, including:
- Oxides of nitrogen (NOx)
- Ozone (O3)
- Carbon monoxide (CO)
- Carbon dioxide (CO2)
- Volatile organic compounds (VOCs)
- …and more
The measured gases can be configured for different instruments. Software algorithms correct cross-interference between species, and a zero-gas generator eliminates drift in the cells.
The Gas sensors are housed in a shielded manifold and aspirated with an ultra-quiet pump, making it suitable for outdoor and indoor air pollution monitoring.
- Records up to 6 gas species simultaneously
- Automatic zeroing virtually eliminates drift
- Integrated with AirQWeb for live monitoring
- Can be used alongside Turnkey dust monitors
- Usable with our solar/wind off-grid power system
How it works
Using 4-electrode electrochemical cells, gas species including NOx and ozone are measured simultaneously with sensitivities of better than 10 ppb, and VOCs (isobutylene) by a 10.6 eV photoionization detector (PID).
A built-in zero gas generator is used to eliminate zero drift in the cells, and software algorithms automatically correct for cross-interferences between the gas species. The zero gas scheme eliminates the effects of changes in relative humidity and ambient carbon dioxide which, in the past, have limited the performance of electrochemical cells at ppb levels.
DustMate
The DustMate environmental monitor is our handheld dust and fume detector and is perfect for short-term sampling.
Versatile and practical, this handheld device is ideal for short-term testing of air quality in buildings, workplaces and on the roadside. With a very fast response time, it delivers accurate readings and can locate sources of airborne dust and fumes even at very low concentrations.
Highly effective for monitoring air quality, the DustMate measures TSP, PM10, PM2.5 and PM1 simultaneously in real-time. It will also continuously indicate the concentration of thoracic, inhalable and respirable particles down to 0.1 µg/m3.
- Internal proprietary ultra quiet sampling pump
- Reference filter for gravimetric calibration
- Ergonomic case allows single-handed operation at arms length
- Internal 32k memory records results
Product Description
User-friendly and easy to set up, the DustMate is perfect for monitoring controlled environments such as cleanrooms in manufacturing plants or scientific research laboratories, where it is essential that low levels of pollutants such as dust and airborne microbes are maintained. In addition to use in buildings, its portability and one-second time resolution make it ideal for use as a roadside indicator to identify high-pollution vehicles as they pass.
Light and ergonomically designed, it allows for single-handed operation at arm’s length while used in handheld mode. If a long sample period is required, the DustMate device can be fixed to a tripod.
How it works
The DustMate, along with our other airborne particle monitors, works using Turnkey’s specially developed nephelometer. Air samples are continuously drawn through the nephelometer, which analyses individual particles as they pass through a laser beam. The particles are then collected on the reference filter. The nephelometer’s microprocessor has the capacity to analyse individual particles even if there are millions of particles per litre.
For reporting purposes, the DustMate can be used with Turnkey’s AirQ or with AirQWeb software. This enables results stored in the DustMate memory to be uploaded to your computer or device when sampling has been completed.
You can also use your computer to control and collect results from the DustMate sensor in real-time.
AlarmBox
Turnkey’s AlarmBox is a controller for dust suppression equipment. It can be set to alert users when predetermined levels of pollutants are reached or exceeded.
The AlarmBox is compatible with all of Turnkey’s dust monitors and can be set up to provide audio or visual alarms.
There is no requirement for an additional computer but it can be configured to work with computer software via a laptop, PC or mobile device with our free software or Android app AlarmBoxApp.
It connects simply to your chosen device via the AlarmBox’s USB point. When configured with the appropriate software the AlarmBox will automatically detect the parameters being measured by the connected air monitoring device.
How it works
With a traffic light warning system, the visual lights are clear and require no explanation. The trigger points can be set at specific levels as required. For example, one alarm could be activated when PM10 > 250 µg/m3 AND (PM2.5 > 20 µg/m3 OR PM1 > 10 µg/m3) AND wind speed > 5 m/s.
The AlarmBox has the capacity to store 16 different scripts, which are saved to its flash memory.
Once a preset level is reached, the alarm will activate. Alternatively, it can be programmed to activate only if a level is exceeded for a specific time period. Depending on the requirements of the end user, this could be an audible alarm, traffic light visual system, or it could be programmed to automatically activate dust suppression equipment.
The software and app can be used to create an alarm scheme based on:
- Dust concentration – any combination of TSP, PM10, PM2.5 or PM1
- Wind speed
- Wind direction
