What is the OC-905 gas detector ?
OC-905 Portable Helium He gas detector designed with the inner pump and the famous brand sensors, with stable performance and high accuracy. It can directly display the gas concentration data on the screen, the data also could be exported to the computer by USB cable.
What is the feature of OC-905 gas detector ?
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 %vol, ppm and mg/m3.
The circuit installed the four layers of wire, so well anti-interference.
Explosion proof grade is Ex ib ⅡC T4 Gb.
What is the funtion of OC-905 gas detector ?
Inspect the gas concentration and alarm when it reaches preset alarm level.
High accuracy, good stability and good repeatability, long working life.
One-key operation to restore to factory default setting.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
The built-in pump, stable flow rate, can be opened or closed;
