Products | KET-AIR-310

ModBUS sensor for air quality and particulate matter measurement

The KET-AIR-310 completes the range of air properties with the detection of particulate matter PM1, PM5 and PM10.

The CO2 measurement works on the basis of the indirect method using MOX technology sensor, which measures the amount of hydrogen in the air and from that estimates the amount of CO2. In addition, combined with the sensor measuring the percentage of Volatile Organic Compounds (VOC), it allows you to take appropriate measures to increase and improve the efficiency of ventilation and air purification.

The KET-AIR-310 also features high-precision temperature, relative humidity and light sensors and uses an RS485 ModBUS RTU Slave interface.

The .DY version with display provides users with rich information on the degree of thermal comfort in the environment. The innovative zero-power e-ink display ensures excellent readability and allows continuous display of the parameters.

The KET-AIR-310 includes an internal memory (.DL version) that can store over 60,000 data points in case of a data communication failure, automatically re-transmitting the data as soon as possible.

Designed to integrate easily into supervisory and energy management systems (BMS / BEMS), it provides a simple user interface. Suitable for use in public environments, it supports keypad lock and limitation of active functions.
