The mV-HR TruTrack Data Logger is a small, 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.
**Older models were known as “Nomad” Data Logger
