TGE-0011, CO2 Logger for Indoor Air Monitoring
The CO
2 logger measures and records the readings of carbon dioxide concentration in the ambient air.
Carbon dioxide is a measure for indoor air quality, and thus, for the quality of ventilation and of HVAC systems. CO
2 concentrations above 1000ppm can cause problems of well-being and health risks in the long run.
Whilst for the most applications the range of 0-2000ppm is sufficient, this version with 0-5000ppm is suitable for more specialized situations, i.e. for expert opinions.
The CO
2 loggers are user-friendly and reliable, accurate, cost- effective and ideally suited to applications such as building monitoring, where it can play a key role in helping to veryfy that ventilation systems are performing correctly.
Self-calibration: The logger uses a self-calibrating NDIR sensor. This uses an infrared source to accurately measure the carbon dioxide concentrations in an application. Over time, the properties of the infrared source will change, so the sensor uses a second infrared source, that is only powered up occasionally, to calibrate the first. This patented measurement technique allows for excellent long-term accuracy and stability.
For the operation of the datalogger you need the Tinytag Explorer software and a USB interface cable.
These you can order additionally as a software starter pack 5.
