Earlier Alarm, Faster Fire-fighting, Less Loss.
1. Overview
The D610 series is a self-developed 4-20mA traditional combustible gas detector. It supports a variety of detection principles such as infrared, catalysis, electrochemistry, PID, semiconductor, etc., and combines intelligent sensor technology and temperature compensation technology to continuously and accurately detect the environment. The leakage concentration of hazardous gases and unique sensor life cycle management make on-site maintenance simpler and more convenient.
This detector meets gas explosion-proof Exd ibⅡC T6 Gb, dust explosion-proof Ex tD ibD A21 T80℃ dual explosion-proof level, IP66 protection level, the shell is made of aluminum alloy or SS316L stainless steel, has good corrosion resistance, especially suitable for petroleum, Used in chemical industry, metallurgy, electric power and other industrial places.

3. Main Features
Accurate detection: can accurately detect more than 50 kinds of normal alkane gases, special gases and VOCs
Never poisoned: There is no safety hazard caused by the "easy poisoning failure" of the catalytic sensor
Resistance to corrosion and deformation: Effectively avoids the corrosion and deformation of the sensor housing and seizure of the probe body in strongly corrosive environments making maintenance and replacement impossible
The readings are intuitive and visible: Gas concentration is intuitively visible on the instrument panel, and can be read from a distance, making it easy to operate
Ultra-long life: The sensor can be used continuously for 8 to 10 years
Stable and easy to use: simple maintenance, no need for frequent calibration
Easy calibration and maintenance: Intelligent hot-plug design, with explosion-proof and intrinsically safe double certification, convenient calibration, maintenance and on-site replacement
