Product Description

Platinum Wire And Rod

Surepure's platinum wire is RoHS compliant.

Standard diameters range from 0.001" (smaller than a human hair) to 0.125".

We use the term "wire" for smaller diameters that are supplied on a spool or as a coil.

We use the term "rod" when the diameter is large enough that it can be supplied as a straight length.

Platinum Use in Thermocouples and Resistance Thermometers

A thermocouple is a temperature-measuring device consisting of two different types of conductor wires. Platinum and Platinum-Rhodium thermocouples are a very stable type of thermocouple and can be used at high temperatures, up to 1800°C (3272°F), depending on the type of thermocouple.

Type B thermocouples are made up of Platinum 70% / Rhodium 30% wire paired with Platinum 94% / Rhodium 6% wire, and can be used up to 1800°C (3272°F).

Type R thermocouples are made up of

Platinum 87% / Rhodium 13% wire paired with Pure Platinum wire, and can be used up to 1600°C (2912°F).

Type S thermocouples are made up of Platinum 90% / Rhodium 10% wire paired with Pure Platinum wire, and can be used up to 1600°C (2912°F).

Before 1990, Type S thermocouples were used as the standard international thermometers from 630°C to 1064°C.
