Multi gas detector with inner pump

OC-903 portable multi gas detector with the imported sensor, for 1~4 gas detecting. It hold 4 sensor at most, including the gas sensor , and also support other type sensor, such as the Temp/humidity sensor(optional). For the multi gas detector, usually for the composite of CO, O2, H2S, LEL.  Common applications include chemical industry, petroleum, gas station, metallurgy, agriculture, biology pharmaceuticals, power, lab research and other industry environment where need to inspect combustible or toxic gas concentration. 

Features:

Data logger function, history inspection data could upload to the computer.

Auot-test and data recovery function.
