Foul Odor Online Monitor

The Odor Online Monitor is independently developed and produced by our company, capable of simultaneously monitoring hydrogen sulfide, ammonia, TVOC, wind speed and direction, etc. It adopts a diffusion method, converting the gas concentration signal at the monitoring point into an electrical signal in real-time. This signal is amplified, sampled, and temperature-compensated, then processed through intelligent calculations. If the measured value exceeds the set alarm concentration, an alarm signal is triggered. This odor online monitor features advanced technology, high performance stability, can output 4-20mA and RS485 signals, and is easy to install and maintain, greatly meeting the high reliability requirements of industrial site safety monitoring. It is widely used in various places such as indoor chemical workshops (chemical plants, pharmaceutical factories), chemical and pharmaceutical warehouses, electrical and cosmetics factories, food factories, wineries, bakery workshops, laboratories, research institutes, etc.
