Turnkey Instruments Ltd

Over recent years Turnkey Instruments research & development team have been busy designing, developing and manufacturing two new market leading air pollution monitors. The newest Monitor to the range is the iPM Particle Monitor, specifically designed for use within local authorities for measuring and reporting Diesel fume pollution.

This Monitor can be permanently mounted and is Ideal for contamination control, through its leading edge technology the monitor offers independent online data management. To further support the monitors market recognition we have applied for MCERTS for PM10 & PM2.5 which is pending.

The next generation of iGASair is a new internet gas Monitor. Its multiple gas sensors are housed within a shielded manifold and aspirated with an ultra-quiet pump, making the instrument equally suitable for both outdoor and indoor air pollution monitoring. Typical sensitivities are given below. Carbon dioxide is detected by means of

Why Turnkey Instruments?

a nondispersive infrared (NDIR) detector, VOCs (isobutylene) by a 10.6 eV photoionization detector (PID), and the other gas species by means of 4-electrode electrochemical cells. A proprietary zero gas generation scheme is employed to eliminate zero drift in all of the gas sensor cells.

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 the air we breathe, and are often present in the same environments, these can be generated by mobile sources e.g. traffic & congestion, h b h stationary sources including Manufacturing plants, Oil & Gas Refineries, factories and area sources from Agriculture.

Both Monitors offer data via pushed and polled technology which delivers data instantly. The Monitors also utilise Turnkey unique Power Portal for mains power, WiFi and 4G/5G cellular connectivity.

All of the Instrumentation is designed & developed by our highly skilled and dedicated UK based in house team of engineers & support team. Our service is unique in that we understand fully the technology we deliver, our R&D team developed the technology, our design team created and manufactured the Monitors whilst our trainers and service engineers help our customers to get the best out of their investment.

Customer support is our top priority, calibration and technical advice is always on hand. Once you have invested in our Monitors our service engineers are available to carry out prompt repairs, on going servicing and product updates. At Turnkey Instruments we understand and prioritise Data Management as this is critical to managing the environments.

Our Monitoring and testing equipment is used with our AirQ Software and associated Apps. This software has also been designed and developed in house, its focus is client centric with functionality and use-ability at its core.
