AERASGARD® KLQ-CO2 - Modbus(LCD)Patented quality product (patent no. DE 10 2014 010 719.1)The maintenance-free duct sensor AERASGARD® KFTM - LQ- CO2 - Modbus (max. expansion level) and KCO2/ KLQ - CO2/ KFTM - CO2 - Modbus with Modbus connection, automatic calibration, in an impactresistant plastic housing with quick-locking screws, plastic sinter filter (replaceable), incl. mounting flange, optionally with/without display, for determining the CO2-content of the air (0...5000 ppm), of the air quality (0…100 % VOC), the temperature (–35...+80 °C) and the relative air humidity (0…100 % RH). International system of units SI (default) can be changed to imperial (via Modbus). The following parameters can be accessed via the Modbus: Temperature, relative humidity, air quality (VOC), carbon dioxide (CO2) and atmospheric pressure. The sensor is used in offices, hotels, convention centres, apartments, shops, etc. for the purpose of evaluating the indoor climate. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being. One sensor for every 30 m2 of space is recommended.
