PROTRONIX NL-ECO-CO2 room CO₂ sensor

Get to know our range of CO2 sensors that ensure optimal indoor air quality — whether it’s an office, a conference hall, a school classroom or a private bedroom. We develop and manufacture CO2 detectors in the Czech Republic, with a primary emphasis on quality as well as universality of use. Thanks to this, our carbon dioxide sensors are compatible with 99% of ventilation units and will last reliably for more than 10 years. In addition, they do not require any maintenance or calibration during the entire period of operation. Our carbon dioxide sensors have a selectable measurement range, from 400 up to 5,000 ppm. We offer sensors in a wide range of supply voltages from 12 V, and the offer also includes models suitable for use in smart-building concepts. Read more about why to use air quality sensors.
