XA 900 Multi gas Detector
XA 900 is a multi gas detector that can be used for the detection of oxygen, combustible gases, hydrogen sulfide and carbon monoxide. The instruments in this series works on different principles, including – catalytic combustion, galvanic cell and electrochemical cell. Available at industry leading prices, the device offers reliable performance and accuracy.Features:
- A range of gas variations are possible by combining detected gases. Fifteen combination patterns are possible.
- Long service life has been achieved through greatly reduced power requirements. No need to change battery for 48 hours when using combinations with combustible gases, or for 2,000 hours when using combinations without combustible gases.
- Used as a Extractive type when connected to "Mini" Multi-gas Detector XA-900 series (for one gas and two gases only).
- Can be used to detect gas in pits or manholes (for one gas and two gases only).
