IGas Air

iGASair Gas Sensor by Turnkey Instruments

Records 8 Gas Species Simultaneously, Easy Recording & Reporting of Multiple Gas Species. iGASair connects to Turnkey’s AirQWeb Cloud Server, Call Now!

iGASair is our web gas screen, which can gauge 8 unique gas species all the while.

iGASair associates with Turnkey’s AirQWeb cloud server, and can be utilized nearby our scope of residue and vibration and clamor instruments to permit coordinated observing of an extensive variety of natural estimations. Gas sensors are housed in a protected complex and suctioned with a ultra-calm pump, making it reasonable for outside and indoor air contamination observing.

  • Records up to 8 gas species simultaneously
  • Integrated with AirQWeb for live monitoring
  • Automatic zeroing virtually eliminates drift
  • Can be used alongside Turnkey dust monitors

How iGASair Works

Using 4-electrode electrochemical cells, gas species including NOx, ozone and sulphur dioxide are measured with sensitivities at the same time of better than 10 ppb. Carbon dioxide is computed by a nondispersive infrared (NDIR) sensor, and VOCs (isobutylene) by a 10.6 eV photoionization detector (PID).

A built-in zero gas generator is used to remove zero drift in the cells, and software algorithms instinctively correct for cross-interferences between the gas species. The zero gas scheme eliminates the effects of changes in comparative humidity and ambient carbon dioxide which, in the past, have restricted the performance of electrochemical cells at levels of ppb.
