PLT-TH2000 VOCs Gas Online Pretreatment Monitoring System
The online pre-treatment and monitoring system for volatile organic compounds (VOCs) can be used in places where the concentration of TVOCs is detected. It can monitor 1-10 types of flammable, toxic, and hazardous compounds, and alert the police once the concentration of a compound exceeds the standard, accurately detecting the concentration of TVOCs and showing the real-time concentration value in the field, and outputting standard signals with the advantages of stable signals, high sensitivity and precision.The standard signal output has the advantages of signal stability, high sensitivity and accuracy, and the explosion-proof wiring is suitable for use in various hazardous locations.
The TVOC online filtering detection system adopts the internationally recognized high-precision PID photoionization detection principle and built-in suction pump mode of operation, featuring fast response time, high precision, long service life, wide range of detected substances, and strong resistance to interferences, etc. The system is equipped with a 4-20mARS485 standard output signal and can be easily integrated into a monitoring system.
