Ammonia Odor Concentration Farm Garbage Station Odor Gas Detector Nh3 Gas Detectors

Product Description

Introduce
      The YF-8500 series fixed detector adopts a diffusion sampling method, and the detection principle is that when the target gas enters the gas sensor, the internal sensor will immediately emit an induction. Sensors generate certain electrical signals based on the concentration of gas. After being amplified by the circuit, the signal is processed by the CPU through AD sampling, temperature compensation, and intelligent calculation to output gas concentration data. It outputs 4-20mA signals, RS485 communication signals, and can be matched with ZIGBEE, NRF, WIFI wireless signals, etc. Customers can collect these signals and use them in conjunction with gas alarm control host, PLC, DCS, upper computer and other systems to trigger alarms
