1. Brief introduction
BS03 fixed gas detector, adopting high-quality catalytic gas sensor and
SMD arts and crafts, has advantages of good reproducibility, disturbing-proof
against temperature and humidity, long life-span and easy operation.
The signal output of BS03 is standard 4-20mA. It is widely used in
refineries, chemical plant, LPG station, gas boiler, and Spray-Paints etc where
gas leakage easily.
