Description
Temperature and CO2 concentration converters with RS232, RS485 outputs are specially designed for indoor use in the creation of energy management systems and HVAC systems. The large two-line display can be turned off if necessary. The converter is intended for use in a non-aggressive environment. The CO2 measurement principle is based on the NDIR (nondispersive infrared sensor) method. It automatically compensates for sensor aging. Auto calibration of the sensor leads to excellent measurement accuracy across the entire operating temperature range.
Recently, the level of carbon dioxide is considered one of the most important parameters responsible for indoor air quality. Especially in buildings and rooms with large gatherings of people, such as conference halls, hospitals, schools, cinemas, theaters, and wellness centers.
With the help of CO2 sensors, engineers, environmental experts, and healthcare specialists can optimize ventilation to create a comfortable and "Healthy" indoor climate.
ATTENTION, the device is currently discontinued.
