Overview
The portable nitrogen dioxide gas detector is used for portable and fast detection of the concentration of nitrogen dioxide gas, temperature and humidity measurement (optional), and alarms for exceeding standards. The 3.5-inch high-definition color screen is used to display the concentration in real time, and imported brand gas sensors (Honeywell, Japan Fundamental, British CITY, British Alpha, British Dynament, Swiss Membrapor, etc.) are selected. The main detection principles are: electrochemistry, infrared, catalytic combustion, Thermal conductivity, PID photo ion. It can detect the gas concentration in the pipeline or in the confined space and the atmospheric environment. It can detect the gas leakage or the purity of a high-concentration single gas with nitrogen or oxygen as the background gas. It can detect more than 500 types of gases.
Features
- Waterproof, dustproof, explosion-proof, shockproof, intrinsically safe circuit design, anti-static, anti-electromagnetic interference, passed the national standard test and CPA measuring instrument type certification
- Protection level IP66, corresponding accessories can be selected for use in high humidity and high dust occasions
- Built-in pump-suction measurement, quick response, sampling distance greater than 10 meters, special gas path design, optional related accessories can detect positive pressure or negative pressure -0.3～2kg gas, no influence on the measurement result
- The 3.5-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage,
communication, printing, power, charging status and other information.
