Advantages of detector
1. High precision
Its precision is better than most of common detectors such as infrared detectors. For the organic gases, the high-precision photo ionization detector can detect the ppd gases.
2. No damage to the detected gas
The photo ionization detector can ionize the absorbed gas; after electric discharging, the ions produced by the gas molecules will restore to the original gas molecules, without damage to the original gas molecules.
3. Rapid response
Apart from the preheating time after the gas detector starts, the photo ionization detector can almost make a response at real time and conduct the continuous test under the normal working condition. For the detection of hazardous gases, it is vital for the health of detection personnel.
