HANWEI VOCScan800 Fixed VOC Detector

PRODUCT FEATURES

• Automatic / manual zero calibration, manual zero calibration on site
• Equipped with many selectable functions
• Multiple detection ranges (0.0-100.0ppm, 0-1000ppm and 0.00-20.00ppm)
• Default factory detection range is 0.0-100.0ppm
• Built-in intelligent processor can manage multi-port valves and regulate the flow of clean air to the detection air chamber
• With self-cleaning function, the detector can wash away the pollutants in the sensor through the circulation of clean air, which ensures the measurement accuracy of the sensor, thereby reducing the workload of on-site maintenance.
• End user can set the time of self-calibration and self-cleaning cycle
• Cleaning Interval / Self-Zero is 60 minutes

APPLICATIONS

This product is suitable for a variety of scenarios, such as petrochemical refining, synthetic fiber manufacturing, gas leakage collection and environmental protection information detection.
