Description:
OC-905 Portable TVOC gas detector designed with the inner pump and the imported brand sensors; it has following advantages of 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.
Features:
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 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.
High accuracy, good stability and good repeatability, long working life.
Reachargeable battery with big capacity.
Data storage and data logger function.
