CH4 Portable Gas Leak Detector
Introduction
BH-90E portable gas detector is a new type of gas leak detector
that adopts LSI technique and meets international smart technology
standards. With imported high quality semi-conductor sensor and
embedded microcontroller, it detects gas leakage with high
sensitivity and strong adaptive ability. Being waterproof,
dustproof, explosion-proof, and easy to use with high reliability,
the detector is widely used in oil, coal, municipal construction,
chemical engineering, environmental protection, metallurgy,
refining, gas transmission and distribution, biochemistry,
agriculture, pharmaceutical industries.
Gas Detected:
*MCU control, low consumption
*High resolution STN LCD
*Housing made of high strength engineering plastics and compound
anti-slip rubber
*Detection range (low alarm point, high alarm point) adjustable
*Low battery alert, intrinsically safe design
*alarm types: sound (mute mode also available), light and vibration
*Gas calibration completed by the factory
*Zero adjustment and data logging
