Principle
Formaldehyde detector adopts the principle of catalytic combustion detection and detects gas concentration by diffusion Sampling method. The detector converts the detected gas concentration signal into 4~ 20mA analog signal, RS485 digital signal or switching signal output through MCU chip processing.
Applications
Workplace environment Gas detection, industrial process control, safety monitoring, environment monitoring
