Detail Gas Monitor IGAS Air Merk TURNKEY INSTRUMENTS (Alat Laboratorium Udara)
iGASair Internet Gas Monitor. (Alat Laboratorium Udara)
iGASair is new internet gas monitor from Turnkey. its mutiple 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 polution monitoring. typical sensitivities are given below .
Carbon Dioxide is detected by means of nondipersive 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.
