Tinytag Carbon Dioxide Data Logger

About this product

The TinyTag Carbon Dioxide Data Logger monitors and logs carbon dioxide levels using an infrared sensor. It can be used in experimental situations or simply to monitor air quality within buildings to ensure that ventilation is effective. The logger possesses a self-calibrating NDIR sensor consisting of an infrared source. A second infrared source is powered up occasionally to calibrate the primary sensor and this patented calibration technique ensures excellent long-term accuracy.

The Carbon Dioxide Logger is housed in a discreet case and is powered by the mains using the power adaptor provided. In the event of a power failure a red LED informs the user that there is a problem. Two models of the Tinytag Carbon Dioxide Data Logger are available. The standard version, TGE-0010, has a measurement range of 0-2000ppm and the wide-range version, TGE-0011, is capable of measuring 0-5000ppm.

To download data from this logger a USB cable and Explorer Software will also be required.
