Hanzel Instruments

The fixed 4-in-1 Multi-Gas Detector can be used to continuously monitor the concentration of a single gas in the file for 24 hours.
There are more than 500 types of detection.
Detector Description

A fixed 4-in-1 Multi-Gas Detector can meet the gas detection site sound and light alarm prompt, and real-time display monitoring site gas concentration, on-site debugging using infrared remote control type, without opening the cover can be set parameters, gas detector using originally imported sensors and new 32-bit low-power processor, the instrument can choose 4 ~ 20mA or RS485 output signal, with accurate detection, long transmission distance, strong anti-interference It has the advantages of accurate detection, long transmission distance, strong anti-interference, etc. With 2 groups of passive relay outputs, it can control fans, sound and light alarms, solenoid valves, and other equipment. Fixed installation, and detection of industrial site combustible and toxic gas leaks using a split-wire system and alarm controller connection to use.
