Portable PH3 phosphine gas detector adopts high‑precision electrochemical sensor, real‑time concentration display, triple sound‑light‑vibration alarm, support 100,000 groups of data storage, ideal for grain depot, fumigation operation, chemical plant and pest control safety inspection.
Product Description
This portable PH3 (Phosphine) gas detector is developed for detecting highly toxic phosphine gas in industrial and storage scenarios. PH3 is widely used for grain fumigation and pest killing, improper operation will cause toxic gas leakage and threaten personnel safety.
Equipped with high‑performance electrochemical sensor, the unit achieves fast response and stable detection data. Real‑time LCD shows gas concentration; sound‑light‑vibration triple alarm will trigger once exceeding preset threshold. Built‑in large‑capacity storage supports 100,000 groups detection data recording for checking and exporting. Explosion‑proof compact handheld design makes it easy to carry for on‑site field work.
It provides reliable safety protection for fumigation operators, grain depot staff and chemical workers, effectively avoiding safety accidents caused by phosphine gas leakage.
Features:
Used original imported sensors and ultra-low power 32 bit microprocessor
The circuit adopts 4-layer wiring, which is stronger for weak signal processing and anti-interference ability
Intelligent algorithm + multi-point calibration + temperature compensation, more accurate measurement results
2.5 inch dot matrix display interface,reading intuitively
All English operation menu and easy operation.
Function：
Inspect the gas concentration and alarm when it reaches preset alarm level.
High accuracy, good stability and good repeatability, long working life.
One-key operation to restore to factory default setting.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
The built-in pump, stable flow rate, can be opened or closed.
