The SGX Sensors series of PS1 and PS4 Electrochemical gas sensors are using a revolutionary ’Solid Polymer Electrolyte’ technology that is based on the principle of catalytic reaction. The target gas to be measured generates a very small current, proportional to the gas concentration. Our technology offers a stable, high quality and cost-effective manufacturing process. The SGX solid polymer electrolyte gas sensors are available in a very small size, are highly sensitive, do not use power and have very low cross sensitivity from other gases.

Sensitivity 35 ± 20 n A / ppm

Measurement range 0 – 5 ppm

Zero current ± 2 nA

Maximum overload 100 ppm

Response time T50 < 20s, T90 < 120s

Repeatability 1% Lower

Lower Detectable Limit (LDL) ≤ 0.05 ppm

Linear range 5 ppm
