Arsenic Hydride Detector for Metal Ores

The metal mine arsine detector uses a chemical reaction to cause arsine to develop color with a reagent, and a photoelectric detector measures the color change to determine the concentration. It is used for monitoring arsine gas in mine safety to prevent poisoning of workers.
Selection
Select an instrument with a detection range covering 0–10 ppm, using the national standard chemical colorimetric method. It should have a response time of less than 3 minutes, equipped with data storage and audible/visual alarms. Consider a portable design suitable for field environments, with regular calibration and maintenance.
