Overview

Formaldehyde detector is designed for real-time monitoring of formaldehyde in the environment（CH2O）High precision safety equipment designed for concentration, suitable for industrial scenarios with formaldehyde leakage risks and environmental monitoring fields. It achieves precise detection through electrochemical sensors, which can quickly respond to concentration changes and trigger sound and light alarms, effectively preventing poisoning accidents and environmental pollution.

working principle

Formaldehyde gas detector is an instrument used to detect formaldehyde concentration. Its working principle is mainly to convert the physical or chemical non electrical signals collected by the gas sensor into electrical signals, and then collect and process the electrical signals through external circuits. When the gas concentration exceeds the alarm set value, external devices can be automatically activated(Such as exhaust fans, solenoid valves, sound and light alarms, etc),And realize remote networking to achieve centralized display of gas concentration and other functions.

The principle of detection technology varies depending on the type of gas being detected. The main principles include electrochemistry, catalytic combustion, ultraviolet ionization, infrared, thermal conductivity, semiconductors, lasers, etc.
