GRI-9105.GRI- 9106 is a high performance intelligent infrared gas detection alarm which developed by our company, high performance, supply couples of types of gas detection.
low power microprocessor to ensure product performance and stability, realtime monitoring of the concentration of infrared gas.
Applicated 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.
1)Three kind of signal output, RS485 and 4~20mA (three wire) digital / analog signal and switch at the same time.
2)Big screen segment type LCD real-time display gas concentration.
3)Gas concentration unit optional (such as ppm, mg/m3), it have the instrument status, fault and communication abnormality prompt function.
4)It can be set high and low alarm point, two level sound and light alarm.
5)Two relay to control peripheral devices (such as the action of machine and sound and light alarm).
6)Round casting stainless steel housing is suitable for offshore platforms, as well as high temperature, high humidity and other harsh environments.
7)Good sealing, anti-corrosion, explosion-proof and anti EMI, RFI function.
8)Supporting use of our company 's GRI-9800 series alarm host.
9)European design standards.
