Retherm is a utility application designed for Android users to convert resistances from RTD sensors into temperature readings. It supports conversions for Pt100, Pt500, and Pt1000 resistances across a wide temperature range from -200°C to +850°C, adhering to European/DIN standards. The app boasts a high degree of accuracy with a minimal margin of error, making it a reliable tool for professionals needing precise readings. Additionally, it offers an American standard conversion option for temperatures ranging from 0 to 100°C, albeit with a slightly higher margin of error.

In addition to RTD conversions, Retherm also facilitates the conversion of thermocouple voltages into temperature values using NIST polynomial equations. It supports various thermocouple types including B, E, J, K, N, R, S, and T, with results displayed in both Celsius and Fahrenheit. The app further enhances user experience by providing links to essential resources about RTD sensors, making it a practical choice for quick reference in the field.
