Hand-held Thermometer with Inbuilt Data Logging/Graphing

Product Code: HDT-EPAD-TC

Robust, easy-to-use hand-held device that records temperature readings to integrated memory via the attached Type K probe supplied with the unit. The large, colour TFT touch-screen indicates temperature, maximum and minimum readings and can also produce a graph of the data. 

The HDT-EPAD-TC has two functions: ‘Data Logging’ and ‘Spot Measurement’.

  • When in ‘Data Logging’ mode it can be set up and left to take temperature readings at pre-determined intervals for a desired length of time. All readings are saved to a file with a date and time stamp in CSV format for up to 65,536 readings.
  • When in ‘Spot Measurement’ mode the unit can be used as a thermometer to capture one-off temperature readings displayed on screen. This can be repeated for up to 65,536 readings per file.

If required, data can also be downloaded to PC via the USB connection (cable supplied) and opened within Microsoft Excel® or the free EasyLog USB software, available for download using the link below.

The unit is compatible with any K, J, T and N type thermocouple probes.

A protective rubber case (HDT-PAD-CASE) is also available to protect the unit from scratches and light knocks.

Please note: the HDT-EPAD-TC is a standalone unit and can record and display data independently of external software.
