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.

Options

Pump Unit

Used as a Extractive type when connected to "Mini" Multi-gas Detector XA-900 series (for one gas and two gases only).

Throw-in Set

Can be used to detect gas in pits or manholes (for one gas and two gases only).
