How much data can be logged before the Q-TRAK Plus runs out of memory?
The data logger can store 63,000 measurements of CO2, temperature, humidity and CO. This means that the Q-TRAK 8550 (without CO) can store 14 days of data taken at 1minute intervals and the Q-TRAK 8551 (with CO) can store 10 days of data taken at 1-minute intervals. Logging intervals may be longer or shorter as set by the user. It is also possible to record only one or two of the measurement parameters if longer logging time is needed. • How often is calibration required for the CO2 sensorCalibration of the CO2 sensor is recommended monthly and can easily be done in the field.
