QB3000N series gas detector detects gas concentration by natural diffusion sampling. It uses high-quality sensors with good sensitivity and excellent repeatability. LED digital tubes display the concentration of leaked gas in real time. When the preset alarm point is exceeded, the sound and light alarm signal or the exhaust system is immediately activated. International standard 4-20mA signal and standard RS485 Modbus digital signal are used. The instrument adopts embedded microcontroller technology, which is simple to operate, fully functional, highly reliable, and reliable overall performance. It has been widely used in underground integrated pipe corridors, petroleum, chemical industry, metallurgy, refining, gas transmission and distribution, biochemical medicine and water treatment industries.
