iGas Air Pollution Monitor

iGas Air Pollution Monitor

iGAS® internet Gas Monitor
iGAS® is a new internet gas monitor from Turnkey®. Its multiple gas sensors are housed within a shielded manifold and aspirated by means of an ultra-quiet pump making the instrument equally suitable for both Outdoor and Indoor Air Pollution monitoring. Typicalsensitivities are given below. Carbon dioxide
is detected by means of a non-dispersive infra-red (NDIR) detector, VOCs (isobutylene) by a 10.6eV photo-ionization detector (PID), and the other gas species by means of 4-electrode electrochemical cells. A propriety zero gas generation scheme is employed to eliminate zero drift in all of the gas sensor cells.

Species Lower Detection Limit Full Scale
NO2 10 ppb 5000 ppb
NO 15 ppb 5000 ppb
SO2 4 ppb 2000 ppb
O3 4 ppb 2000 ppb
CO 4 ppb 2000 ppb
H2S 1 ppb 2000 ppb
CO2 1 ppm 5000 ppm
VOC 5 ppb 50 ppb
