Description

Built-in advanced iVOC sensor is sensitive to volatile organic substances typically contained in the stuffy air – gaseous metabolic products of human bodies and other gaseous pollutants such as formaldehyde, cooking vapors, fumes from paints, varnishes, adhesives, detergents, etc. that CO₂ sensor does not detect. NL-iVOC sensor detects gaseous pollutant substances in the air that are the main reason for ventilation. Sensor NL-iVOC approximates to human perception of air quality. The output of the sensor is calibrated as equivalent to a standard CO₂ sensor.

Measurement of the relative humidity is based on the principle of capacitive polymer sensor.

The sensor has built-in two separate analog outputs – one for the actual concentration of VOC and the other for the current relative humidity. Sensor also contains one relay. Relay´s response – VOC or RH can be set by shorting jumper. Level of air quality at which the relay switches can be easily adjusted by the rotary switch. Current air quality can be easily checked the by three LED indicators. Eco level means good indoor air quality needed to achieve a sense of well-being together with optimizing energy costs for heating or air conditioning.
