Carbon dioxide detector / handheld carbon dioxide detector Model: HAD-HC0201 The main performance and features: · The most reliable NDIR infrared sensor · Large range detection range · Quick response · Large data storage · Alarm and time setting function · USB interface high speed data download · No warm-up time Automatic backlight display · User self-calibration calibration mode · Simple operation and safe use · Digital temperature and humidity sensor The HAD-HC0201 handheld direct reading digital carbon dioxide (CO2) tester is an analytical instrument based on a new type of dual-beam dual-wavelength non-dispersive infrared NDIR sensor. Makes the instrument with high resolution and more accurate in the detection process, long-term stability, good linearity and easy calibration calibration. Direct-reading digital CO2 analyzer instrument consists of non-dispersive infrared NDIR sensor, sampling pump and microprocessor, which can accurately and quickly measure the CO2 concentration in public places and indoor and outdoor. It can perform continuous real-time environmental monitoring and analysis. The percentage of CO2 in the sample under test is displayed on the backlit LCD screen. The built-in external high-precision digital temperature and humidity sensor can display the measured environmental conditions and be used for compensation to improve the test accuracy. The data can be passed. USB download. It can be widely used in continuous pollutant monitoring systems (CEMS), environmental protection, health and epidemic prevention systems, and air pollution and greenhouse effect detection.
