CO2 sensor with optical and acoustis warning signal for measuring the indoor air quality
The indoor air quality guard LGW-13 is a versatile CO2 carbon dioxide sensor with a 10-digit LED display and a warning horn. Furthermore, the device has a 4...20mA and 0...10V signal output and a floating signal output.
The amount of Carbon Dioxide CO2 in the fresh air is only about 0,034& but is used as an indicator for the indoor air quality. A carbon dioxide concentration of 1000ppm (0,1vol%) is the limit for clean air in rooms.This limit is known and called as the "pettenkofer number".
The indoor air quality guard LGW13 as a CO2 detector and sensor has been specially designed for the measurement and monitoring of ambient air quality. The air quality is represented by a 10-digit LED bar graph display. In addition to the current output and voltage output of the LGW-13 has potential free floating switching output as well as an audible alarm detector for CO2 measurement indoors. The combination of a very accurate CO2 measuring sensor and a carbon dioxide detector with a easy to use LED Display for the CO2 monitoring as well as different signal outputs make the LGW-13 to a flexible CO2 air quality monitor with a wide range of applications.

Der indoor air quality guard LGW13 and CO2 Sensor has a 10 digit bar graph display that shows the concentration of CO2 carbon dioxide optically. A yellow LED signals the activation of the adjustable CO relay output. Another separate LED in the ventilation slots monitors the function of the CO2 Sensor. Extinction of the LED indicates an error condition of the CO2 sensor.
the LGW-13 has 2 switching thresholds depending on two pre configured CO2 limits. Limit1 switches potential free or a connected 24V ventilation unit via jumper. the acoustic alarm horn sounds depending on the set CO2 Limit2 (a quieter and louder volume level can be selected via jumper).
The air quality guard LGW13 proved itself already widely in practice. Companies from various industries use it as air quality traffic light. In the industry, our innovative device for measuring the air quality and the CO2 concentration is used in combination with ventilation control systems, which we also offer in our product range. The indoor air quality guard LGW-13 contributes to the protection of people and technology, such as the labor and fire protection for staff, machines and plants as well as heating and refrigeration.
