Common customer questions & answers

QQuestion How long do the batteries last?
AAnswer Battery life is dependent on probe type and any logging frequency. In general terms new good quality batteries will last for a couple of hours if undertaking spot measurements, and if data logging we would always recommend the use of the power supply to prevent data loss.
