OC-905 pump suction portable O2 gas detector, high precision oxygen monitor with sound-light alarm, for confined space, tank cabin and underground pipeline oxygen safety detection.
Description:
OC-905 Portable Oxygen O2 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 Hydrogen Sulfide 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 Oxygen 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 %vol.
The circuit installed the four layers of wire, so well anti-interference.
Explosion proof grade is Ex ib IIC T4 Gb.
Function:
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 could be controlled.
