Product Description

Product Description

PLATINUM RHODIUM THERMOCOUPLE

A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end.

When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature. Thermocouple alloys are commonly available as wire.  

Thermocouples are widely used in science and industry; Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes.

Thermocouples are also used in homes, offices, and businesses as the temperature sensors in thermostats, and also as flame sensors in safety devices for gas-powered major appliances.

EXCEPTIONAL LONG-TERM STABILITY

SUPERIOR MEASUREMENT ACCURACY

OUTSTANDING OXIDATION RESISTANCE

Maintains consistent accuracy and calibration over extended periods of continuous use at high temperatures. Platinum rhodium construction resists drift and degradation, providing reliable measurements for years without frequent recalibration requirements.

Delivers precision temperature readings with an accuracy of the measured value. High-grade noble metal construction ensures consistent thermoelectric characteristics and minimal measurement uncertainty for critical applications.

Platinum rhodium alloy provides exceptional resistance to oxidation and corrosion at elevated temperatures. Maintains structural integrity and measurement performance in oxidizing atmospheres where other thermocouple types would rapidly degrade or fail.
