Thermocouples is an Android app designed to provide general information on thermocouples for professionals dealing with thermal sensors. The app is a quick reference guide to thermocouples, featuring the color codes for a wide range of thermocouples in multiple standards, including IEC, BS, ANSI, NFE, DIN, and JIS. The app also includes a built-in temperature calculator for convenience.

Thermocouples is an open-source app released under the MIT license. It is free, requires no permissions, and does not use any user data. The app is designed with a modern material design, and it features a search function to find thermocouples by conductor colors to identify the type and color code. The app also includes a temperature converter with °C, °F, and K, a cold junction °C to mV calculator, and mV to °C converter using NIST values for main thermocouple types.
