Phosphine Gas Detector Alarm

The aluminum phosphide gas detector alarm measures the concentration of phosphine gas in the air through an electrochemical sensor. When the gas diffuses into the sensor, an oxidation-reduction reaction occurs, generating an electrical signal that is processed by the circuit to display the concentration value. When the concentration exceeds the preset threshold, audible and visual alarms are triggered. It is used in locations where aluminum phosphide decomposition risks exist, such as grain storage fumigation and chemical production.
Selection
Confirm that the detection range covers 0–1000 ppm with a resolution of 1 ppm. Pay attention to sensor lifespan and cross-interference data. The explosion-proof rating must meet the operational environment requirements, and the IP protection rating should be suitable for on-site conditions. Check the alarm logging function and calibration cycle. Consider whether pump-suction or diffusion sampling methods are appropriate for the site.
