Hydrogen Detection Alarm Description:
MIC-500S-H2-AJH on-line hydrogen detection alarm is used for hydrogen concentration
detection and hydrogen concentration exceeding alarm, it can accurately detect hydrogen
concentration and display real-time hydrogen concentration value on the spot, sound and light
alarm for exceeding the standard, standard signal output, it has the advantages of stable signal,
high sensitivity and precision, and the explosion-proof wiring mode is suitable for all kinds of
hazardous places.
Features:
.Explosion-proof, lightning-proof, anti-static, anti-reverse connection, anti-EMI, EMC
electromagnetic interference, anti-pulse surge current impact.
. Conform to the latest national standards GB15322.1-2019, GB3868.2-2000, GB/T50493-2019 and obtain the CPA measuring instruments type approval certificate, explosion-proof certification and other qualifications.
.Three-wire, two-wire or four-wire 4-20mA standard signal output (optional with Hart protocol), at the same time with the standard bus system RS485 (Modbus RTU format), 2 groups of relay switching, optional voltage output
.Wireless transmission method can be selected from 433M, LORA, WIFI, 4G/5G, NB-IoT
and so on.
.Standard with infrared remote control.
.Can be connected to computer to monitor the concentration of on-site probe in real time through the upper computer software and store and analyse and print the data on the computer.
.The units can be switched with each other, automatic tracking zero point to prevent drift, multi-level target point calibration.
.Support OEM or ODM customized service.
