JH-VOC Air Quality Monitoring System

JH-VOC Air Quality Monitoring System

1. Product Overview
JH-VOC Volatile Organic Compounds (TVOC) Online Monitoring System is suitable for online monitoring of volatile organic compounds in factory boundaries and unorganized areas. It can also monitor the rapid determination and real-time display of meteorological parameters such as temperature, humidity, atmospheric pressure, etc. in the atmospheric environment. The monitoring data is quickly transmitted to multiple monitoring platforms through the 4G network and synchronized to the computer and mobile phone.
