- Measure the oxygen’s pressure in the air

Oxygen sensor SS2118 (0~30%)

- As the measuring sensor of the oxygen in the air, suitable for the portable equipment and industrial equipment

- Excellent accuracy and response time

Carbon monoxide sensor SS1128

- Fire monitoring application for the portable equipment, industrial safety equipment, boiler room, parking place

- Excellent stability of the output signal and little ffected by other gases

Hydrogen sulfide sensor SS1198

- Suitable to monitor the petrochemical, oil refining, waste water treatment, drain water treatment, manhole, mining

IR (Infrared) Sensor

- Gas measuring Sensor only for the flammable gas and carbon dioxide, nitrogen dioxide

- The Infrared sensor which has Very fast response and excellent accuracy can easure the flammable gas in the nonoxygen space

Hydrogen sensor SS1178

- Suitable to monitor the power plant, hydrogen fuel battery, hydrogen tank, hydrogen leakage and processes

- Minimize the interference on the hydrogen sulfide
