Other PID Sensor 4R-PID

  • Other-PID-Sensor-4R-PID.png


4R-PID is a high-performance photoion sensor. It can detect very low concentrations of VOC gases, and its performance in all aspects is more stable than traditional detection methods.


* Can detect compounds at the parts per billion (ppb) to parts per million (ppm) concentration level.
* Accuracy exceeds infrared sensor and other sensors.
* Most organic and some inorganic gases can be detected.
