KQ-HCHO single point wall mounted formaldehyde alarm

Product Introduction

KQ-HCHO single point wall mounted formaldehyde alarm is a fixed instrument that can continuously detect gas concentration in the working environment.

KQ-HCHO is a natural diffusion method for detecting gas concentration, using imported electrochemical sensors with high accuracy, accurate measurement, anti-interference, stable performance, high sensitivity, and fast reaction time;

KQ-HCHO uses a large LCD screen to display the real-time concentration value of leaked gas. If it exceeds the preset alarm point, it will immediately activate the sound and light alarm signal or drive the exhaust system; The international standard 4-20mA output signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with a simple Chinese menu operation, complete functions, high reliability, and overall performance leading in China.

KQ-HCHO has been widely used in environmental protection, power, chemical, resin, medical, coatings and other fields, and has become an essential protective equipment in industrial safety production.
