Platinum Thermocouple


Made from the finest platinum and platinum-rhodium alloy, these type R thermocouples and type S thermocouples cover a temperature range of 0 °C to 1450 °C with uncertainties as good as 0.15 °C over most of that range. With four different models for each type, we have the type R thermocouple and type S thermocouple to fit your application
