XA 900

FEATURES:

Four (or three) gases can be detected simultaneously by one unit.
Flammable gas Oxygen, hydrogen sulfide, and carbon monoxide can be detected simultaneously by one unit, and hence one unit can cover plural gas sources.

A wide variation
Five kind combinations are available by freely combining three or four types of gas sensors, which can be selected depending on the gas detected.

Ultra-small and ultra-light in four-gas type
In spite of four- or three-gas type, it's very small and light. No extra burden for workers.
