Description
Temperature, humidity, and CO2 concentration converters with RS232, RS485 interfaces and remote probe with various cable lengths (1, 2, 4m). Equipped with two relay outputs for signaling, indication, or control of external devices. Delay, hysteresis, and sound signal settings are included for each relay. Parameters are easily adjustable using a computer or with the control keyboard. The converter is microprocessor-controlled, housed in a durable plastic case with terminal connectors. A large two-line LCD display is designed for simultaneous display of two parameters. The display can be turned off if necessary.
Recently, levels of carbon dioxide, temperature, and humidity are 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.
