CO2 meter with automatic calibration function, suitable for harsh environments and outdoor installation.
● The detection principle recommended by the Ministry of Economy, Trade and Industry is an optical sensor. ● Equipped with automatic CO2 calibration function (automatic correction function). ● Revolutionary long-term stability. ● Temperature compensation function. ● Resistance to contamination. ● Easy installation. ■ The EE820 is a CO2 measuring device designed for harsh applications. ■ It is calibrated for CO2 at multiple temperatures during manufacturing, allowing for accurate CO2 measurements across the entire temperature range and enabling outdoor installation. ■ To compensate for aging degradation, E+E's unique dual-wavelength NDIR CO2 sensor is adopted, which is resistant to contamination and provides long-term stable measurements. ■ With a robust and functional housing equipped with a special integrated filter, it can be used in contaminated environments such as agriculture and livestock barns. For applications requiring rapid response, an air circulation fan is provided, which can be installed on the back of the integrated filter.
