The EPRGC04161 uses a robust long life semiconductor carbon monoxide sensor for high performance carbon monoxide measurement with excellent long-term stability. The metal oxide semiconductor sensor element used in the EPRGC04161 is not affected by any condensation, high humidity or contaminants present in the measure environment. The EPRGC04161 has built-in electronic circuit, which enables digital measurement of carbon monoxide value with temperature compensation logic by continuous monitoring of the ambient air to detect carbon monoxide concentrations. Comfortable calibration routine with selective access release is integrated in the transmitter electronic circuit. As option 2 relays with adjustable switching thresholds are available. It is ideal for many domestic and light industrial applications including kitchens, restaurants, underground parking, loading bays, and warehouses.
