Product Description:
PID-AH PID Optical ion Sensor VOC Detection Sensor Small Range
Features:
PID sensor /VOC detection sensor PID-AH(small range) Product Introduction:
PHOTO IONIZATION DETECTORS can measure VOCs (volatile organic compounds) and some toxic gases in the (1ppb-40ppm) range.
Many hazardous materials contain VOC, PID, because of its high sensitivity to VOC, has become an indispensable practical tool for early hazardous substances alarm, leakage monitoring and so on. Current open
The upgrade of the bulb and the internal IC greatly extends the service life of the bulb.
OEM gas sensors with high-end sensing technology
The PID-AH gas sensor is optimized for extremely low background interference, achieving optimal low-end sensitivity while maintaining a wide dynamic range.
The PID-AH gas sensor is virtually insensitive to changes in humidity and offers unmatched performance in a variety of applications.
Second, PID sensor /VOC detection sensor PID-AH product features
The Small range VOCs Gas sensor -PID-AH is a simple plug and play sensor that provides action to thousands of volatile organic compounds (VOCs) in a variety of different applications
State and reliable response.
The sensor is designed for both diffuse and in-line pumping sampling, providing excellent response times and clearance rates. The sensor uses a bulb with special brightness and stability that can be used at longer lengths
Reliable detection of weakly volatile and undetectable compounds over time.
Key features:
• Moisture resistance
• Anti-pollution design
• Detachable, air-sealed sensor electrode set
• 4 / A series
• 12-month warranty (excluding bulbs and grids)
• Life expectancy > 5 years
