Tinytag Service Calibration includes calibration of your data logger against an instrument of known accuracy, battery replacement and a certificate confirming your data logger's accuracy at the time of measuring.

Calibration is the process of comparing the readings of a measuring device against an instrument that has a known accuracy. For Tinytag data loggers, calibration involves comparing the readings of your data logger with a UKAS-calibrated instrument to determine the accuracy of the data logger.

Data loggers are calibrated at 'calibration points' - specific measurement points within the data logger's measurement range. Loggers can be calibrated at standard points or at points which are specific to your application. This article will help you choose the correct calibration points for your data logger.
