Overview
Emissions and Stack Portable Nitrogen Dioxide Detectors is used for the occasions where rapid detection of nitrogen dioxide gas concentrations, temperature and humidity measurements, and over-standard alarm. It adopts high-definition color screen for real-time display. It is built in imported high performance electrochemical, infrared, catalytic combustion, thermal conductivity, PID gas sensors and high-precision capacitive digital temperature and humidity sensor. Advanced circuit design, mature kernel algorithm processing, unique shape design, has obtained a number of software work patents and appearance patents. It can detect the gas concentration in pipelines or confined spaces and the atmospheric environment. It can detect gas leaks or high purity single gas purity of various background gases such as nitrogen or oxygen.
