Sensitivity 2ppmH2S, nA/ppm 1450~2050

Reaction time t90 from zero to 2ppmH2S (s) <45

When the zero current is 20℃, the output is -250~0 in the zero air

Interference Average interference (ppb) 1

Detection value ppb 1

Range H2S Warranty Detection Range (ppm) 100

Linearity full range error, 0-2ppm linear <±4

The overload responds to the gas pulse stabilization at ppm 200

 

 

Four, hydrogen sulfide sensor (H2S sensor)H2S-B4 life

 

Zero drift The ppm in laboratory air varies from year to year to <±100

Sensitivity drift The annual change in laboratory air has a maximum ratio <20

Working life output drops to 80% of the original signal time (months) (12 months warranty) >24

 

 

Five, hydrogen sulfide sensor (H2S sensor)H2S-B4 environment

 

Sensitivity 2ppm at -20°C, (output at -20°C/output at 20°C) % 77-90
