Portable gas detector

OC-905 Handheld Tetrahydrothiophene C4H8S gas leak detector

OC-905 Handheld Tetrahydrothiophene C4H8S Gas Leak Detector, built-in pump suction, imported precision sensor, 100,000 groups data storage, two-stage audible visual alarm, Ex ib IIC T4 explosion-proof for natural gas odorant leakage inspection.

Description:  

OC-905 Portable C4H8S gas detector designed with the inner pump and the famous brand sensors, with stable performance and high accuracy. Used to detect the single gas concentration for the Combustible gas, Toxic gas, Carbon Dioxide, Oxygen, TVOC, etc. It can directly display the gas concentration data on the screen, the data also could be exported to the computer by USB cable.  

For the portable C4H8S gas detector, the common applications is gas safety inspection and alarm for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, metallurgy, mining, fire, environmental protection, etc., where need to inspect the C4H8S gas concentration.  


Features:

Used the original imported sensor, semiconductor technology of ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip, so with the high accuracy.  

2.5 inch dot matrix display interface.  

All English operation menu and easy operation.  

Unit data available for mg/m3.  

The circuit installed the four layers of wire, so well anti-interference.  

Explosion proof grade is Ex ib IIC T4 Gb.
