iGASair
iGASair is our internet gas monitor, which can measure 6 different gas species simultaneously.
iGASair connects to Turnkey’s AirQWeb cloud server, and can be used alongside our range of dust and vibration & noise instruments to allow integrated monitoring of a wide range of environmental measurements. 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
- Product stand NOT included
Product Description
iGASair is a new internet gas monitor from Turnkey. 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 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.
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.
