About this app

Thermocouple Reference, Information and Calculations

Thermocouples is a reference guide to get general information on Thermocouples for all those in the industry that regularly deal with thermal sensors.

This handy app features the colour codes for a wide range of Thermocouples in a wide range of standards on easy to see images. The shown standards are IEC, BS, ANSI, NFE, DIN, and JIS.

The currently included Thermocouples are B, E, J, K, N, R, S, T, U, Vx.

Also shown is the thermocouple materials used in each leg for the thermocouple as well as the general temperature range. There is also a built-in temperature calculator for convenience.

Thermocouples is now open source. The source can be found at:

Added in version 1.1, The application can now convert thermocouple mV to degrees Celsius using NIST values for a high accuracy conversion using 0°C as a reference temperature.

The converter shows all temperatures at once for the mV input to help with thermocouple identification. The converter currently supports B, E, J, K, N, R, S, T.

From version 1.5 the application can now calculate mV from temperatures (0°C to 70°C) for cold junction calculations.

Main features:

* Shows Thermocouples colours for 10 Thermocouples across 6 standards.

* Information on range, conductor materials and compensates.

* Temperature converter with °C, °F and K.

* Cold junction °C to mV calculator.

* Modern material design.

* Open-source via the MIT licence.

* mV to °C converter using NIST values for main thermocouple types.

* Search Thermocouples by conductor colours to find type and colour code.
