What data logging options are available ?


The flowtherm NT handset can log instantaneous values / long term measuements using the automatic 'AUTO' function, or via the 'START' function which starts logging at a pre set time.  Data can also be collected with a 'START-STOP' mode (timer).


How long do the batteries last ?


This depends on the battery type, but typically x4 Duracell Plus type batteries will last for approximately 24 hours.  If a long term monitoring exercise is to be conducted the instrument can be run via a USB plug in power supply but this not suitable for use in hazardous areas.
