Overview

GAOTEK NO2 Gas Analyzer is used for the occasions where rapid detection of nitrogen dioxide gas concentrations, temperature and humidity measurements, and over-standard alarm are required. The detector adopts a 2.31 in (58.67) high-definition color screen for real-time display. It is built-in imported high-performance electrochemical, infrared, catalytic combustion, thermal conductivity, and PID gas sensors and a high-precision capacitive digital temperature and humidity sensor. It has advanced circuit design, mature kernel algorithm processing, and a unique shape design. It has obtained several software work patents and appearance patents.
