The new series of air quality sensors! The sensors are designed to monitor the quality of the indoor air. They measure carbon dioxide, relative humidity, volatile organic compounds and the temperature in various combinations (carbon dioxide, carbon dioxide + relative humidity, VOC, VOC + relative humidity, relative humidity and relative humidity + temperature). The sensors have analogy outputs 0-10 V / 0-20 mA / 4-20 mA, it is possible to choose the option with the relay, power is 12 to 40 V DC or 14-30 V AC. Complete information about the NEW LINE sensors you can find in a list of products of our company.
