Description
Temperature, humidity, and CO2 concentration converters with RS232 and RS485 outputs. Housed in a reliable, wear-resistant case. There is an option to program the output signal. The large two-line LCD display is designed to simultaneously show two parameters. The display can be turned off if necessary. The measurement principle is based on the NDIR (nondispersive infrared sensor) method. It automatically compensates for sensor aging. Auto-calibration of the CO2 sensor results in excellent measurement accuracy across the entire operating temperature range. This sensor can meet the highest requirements for outdoor use. It is resistant to contamination and provides maintenance-free operation and excellent long-term stability.
Recently, levels of carbon dioxide, temperature, and humidity have been considered as the most important parameters responsible for indoor climate 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 such sensors, engineers, environmental experts, and healthcare specialists can optimize ventilation to create a comfortable and "healthy" indoor climate.
ATTENTION, the device is currently discontinued.
