Principle
The phosphating hydrogen detector adopts the principle of catalytic combustion detection, and detects the concentration of phosphating hydrogen gas in the environment through the diffusion type Sampling method. The detected signal is processed by the MCU chip and converted into a standard signal output.
Applications
Workplace environment Gas detection, industrial process control, safety monitoring
