tempmate.-B mini data loggers

Battery life calculator

The tempmate.®-B mini data loggers have a built-in, non-replaceable battery. The loggers’ life therefore depends on the battery and on customer-specific settings such as sampling rate, resolution or ambient temperature. This calculator will enable you to calculate the minimum expected battery life. With short sampling rates at very high temperatures, it usually makes more sense to take into consideration the number of measurement cycles. Battery life can be optimised further by observing the following:

  • Always choose the maximum sampling rate
  • If sufficient, select a lower resolution
  • After each recording, set the logger to stop
  • If possible, select the ‘Stop when memory full’ option
