TGAS-1031-CH4 HIGH PRECISION METHANE METANA GAS DETECTOR CH4 FLAMABLE

TGas-1031 Series Combustible, Toxic and Harmful Gas Transmitter can continuously measure the concentration of site gas, and convert the concentration signal into 4-20mA output. It is extensively applied in petroleum, petrochemistry, chemical industry, gas, coal, metallurgy and electric power; safety detection in municipal administration, telecommunication and traffic tunnel construction; the place where combustible, poisonous and harmful gas might leak, such as gasholder station and special industrial factory building, etc.

Main features

1.Two kinds of optional mode of power supply, including centralized busbar type and independent area type
2. High and low concentration alarm, performing real-time monitor to gas
3. Anti-poisoning type gas sensor with high sensitivity
4. Automatic modification of ageing curve of sensor, keeping constant alarm sensitivity
5. Function of automatic recognition of sensor trouble, function of high concentration gas above-norm of sensor
6. Function of automatic detection at starting up, and it has advanced function of self-diagnosis and self-reparing.
7. The calibrated concentration value is adjustable, facilitating users to set by themselves
8. When the sensor loses the function of monitoring alarm because of ageing, the detector is capable of automatic recognition and alarm, so as to effectively avoid missing report.
