Description
CO2 concentration converters with RS232, RS485 outputs and a built-in carbon dioxide sensor. Housed in a durable 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. If necessary, the display can be turned off. The measurement principle is based on the NDIR (nondispersive infrared sensor) method. It automatically compensates for sensor aging. The CO2 sensor's auto-calibration results in excellent measurement accuracy across the entire operating temperature range.
The sensors are capable of meeting the highest requirements for outdoor use. They are resistant to contamination and provide maintenance-free operation and excellent long-term stability.
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.
