Hydrogen sulfide detector

Overview:

　　Hydrogen sulfide detectorAccording to the national standard quality requirements, initiate research and development projects. This instrument can meet the requirements of detecting on-site sound and light alarm prompts, and displaying real-time monitoring of on-site gas concentration. The on-site debugging adopts infrared remote control, and parameters can be set without opening the cover.

The point type gas detector can convert the concentration signal of leaked gas in the air into an electrical signal for remote transmission. The instrument adopts a three wire 4-20mA or 4-wire RS485 output mode, which has the characteristics of long transmission distance and anti-interference. The detector is suitable for detecting the leakage concentration of flammable gases and toxic and harmful gases in industrial environments.
