Description
Overview
GAOTek Ozone Pump suction 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 O3 gas detector, the common applications are 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 O3 gas concentration
Features
- 24-bit ADC acquisition chip, so with the high accuracy
- All English operation menu and easy operation
- Unit data available for ppb, ppm and mg/m3
- Explosion proof grade is Ex IB IIC T4 Gb
