Portable VOCs Monitor
Product Documentation:
Monitoring principle:
PID-NDIR
PID-NDIR
Details
Based on the combined measurement principles of PID (Photoionization Detection) and Non-Dispersive Infrared Absorption (NDIR), this system is suitable for VOCs source tracing, rapid detection of purification efficiency in treatment facilities, organized and unorganized on-site emergency detection for enterprises, and pipeline emission leakage detection in chemical plants.
Features
- The monitoring method complies with the requirements of DB44/T1947-2016 and US EPA Method 25B, ensuring stable and highly reliable technology.
- Simple and convenient dual-button operation with ultra-short detection time, enabling rapid and continuous on-site monitoring.
- Dual detectors offer a wide measurement range, excellent and stable sensitivity to most monitoring gases, and strong applicability.
- Compact design with lightweight components and composite materials, making the device small and light for easy portability.
- Built-in polymer lithium-ion rechargeable battery eliminates the need for an external power supply, allowing the instrument to be preheated for quick on-site measurements.
Applications
Applicable to VOCs source tracing, rapid detection of purification efficiency in treatment facilities, organized and unorganized on-site emergency detection for enterprises, and pipeline emission leakage detection in chemical plants.
