The platinum thermal resistance (PTR) uses platinum for determining the temperature. It works on the principle that the resistance of platinum changes with the change of temperature. The thermometer measures the temperature over the range of 200°C to1200°C. The platinum is an unreactive metal and can easily be drawn into fine wires.

The requirements of the International Temperature Scale of 1948 for the purity and physical condition of platinum to be used in resistance thermometry are based upon the change in resistance between 0° and 100°C, this range being known as the fundamental interval: the ratio R100/R0is required to be greater than 1.3910.

Up to 950°C, the platinum resistance thermometer is often used as a reference standard. Above that temperature, up to about 1750°C, a type S (platinum/rhodium-platinum) thermocouple is usually employed. Type K (chromel-alumel) thermocouples are also used as an alternative reference standard for temperature calibration up to 1000°C.

Resistance Thermometers utilise a high precision sensing resistor, usually platinum, the resistance value of which increases with temperature. The dominant standard adopted internationally is the Pt100 which has a resistance value of 100.0 Ohms at 0°C and a change of 38.50 Ohms between 0 and 100°C (the fundamental interval).

Thermometers based on this principle are called resistance temperature detectors (RTDs). Platinum is particularly useful for an RTD because it can be made very pure, is stable and does not oxidize easily, and has a relatively high melting point of 1772°C. In addition, its resistance varies smoothly—nearly linearly—over a wide range of temperatures.
