KET-OFX-110 is a complete environmental sensor able to detect the movement of people in a radius of about 3-4 meters, is equipped with sensors for temperature, relative humidity, light, indirect CO2 and VOC (Volatile Organic Compounds).
The built-in dual light sensor allows you to limit the switching on of lights only below a certain threshold of illumination that can be set remotely.
The sensor in MOX technology works according to the indirect method of CO2 measurement, i.e. it measures the amount of hydrogen and from that estimates the amount of CO2. Combined with the sensor that measures the percentage of Volatile Organic Compounds (VOC), it allows you to take the necessary measures to increase and improve the efficiency of ventilation and air purification.
Moreover, thanks to the infrared transmitter, it can control a wide range of air conditioners and heat pump systems. It is also equipped with an IR receiver for acquiring custom commands.
The ModBUS interface allows the KET-OFX-110 to be connected to SCADA, programmable logic and standard monitoring systems, while the digital dry contact input can be used to connect door/window contacts, PIR sensors or control buttons. These features, together with the convenient e-ink display and the thermostat function for setting the temperature set point and other useful parameters to regulate the operation of the controlled device, make the KET-OFX-100 the ideal device for supervisory and energy management systems (BMS / BEMS).
Suitable for use in public environments, it supports keypad lock and limitation of active functions.
