Model mV-HR

TruTrack data logger The mV-HR is a small, two channel, high resolution (16-bit) voltage data logger, provided with an internal temperature sensor. The unit can accommodate inputs of

±50 mV
±100 mV
±200 mV
±400 mV

Models designed for other voltage ranges, 4-20 mA input, and self-contained loggers for a host of environmental parameters are also available. Please contact us for further details.

Supplied with easy to use yet feature-rich software, the loggers can be programmed to record in engineering units, and yield a number of useful reports. Logging files can be exported to spreadsheet programs, for further analysis.
