The EPDGCO04161 sensing element uses a robust long life Non-Dispersive Infrared (NDIR) technology with the patented self-calibration system to guarantee the long-term stability and up to 15 years life-time for high performance CO2 measurement. The NDIR sensor element used in the EPDGCO04161 is not affected by any condensation, high humidity or contaminants present in the measure environment. The EPDGCO04161 has built-in electronic circuit, which enables digital measurement of CO2 value with temperature compensation logic by continuous monitoring of the air to detect CO2 concentrations. Built-in calibration routine is integrated in the transmitter electronic circuit. It is ideal for many domestic and light industrial applications including office, restaurants, classroom, and supermarket.
