GRI -9106-C-Ex Intelligent Fixed Combustible Gas Detector

Product summarize:

GRI-9106-C-Ex is a high performance intelligent infrared gas detection alarm which developed by our company, high performance, supply couples of types of gas dedection,low power microprocessor to ensure product performance and stability, real-time monitoring of the concentration of infrared gas. Mainly used in petroleum chemical industry, metallurgy, mining, fire, gas, environmental protection, electric power, communication, papermaking, printing and dyeing, food reserves, city water supply, sewage treatment, food, brewing, research, education, national defense and other places.

Main feature:

Three kind of signal output, RS485 and 4~20mA (three wire) digital / analog signal and switch at the same time.
Big screen segment type LCD real-time display gas concentration.
Gas concentration unit optional (such as ppm, mg/m3), it have the instrument status, fault and communication abnormality prompt function.
It can be set high and low alarm point, two level acousto-optic alarm.
Two relay to control peripheral devices (such as the action of machine and acousto-optic alarm).
Round casting stainless steel housing is suitable for offshore platforms, as well as high temperature, high humidity and other harsh environments.
Good sealing, anti-corrosion, explosion-proof and anti EMI, RFI function.
Suppoting use of our company ‘s GRI-9800 series alarm host.
European design standards.
