The thermocouple is used to measure
WebUsed primarily for measuring the temperature of non-corrosive gas when a faster response time is preferred. For use in applications where the fluid or gas being measured is corrosive or otherwise harmful to the thermoelement. Due to the insulation, the response time is slower than that of an exposed junction. WebMeasuring environment Voltmeter. PROBLEM 4: A J-type thermocouple is used to measure an unknown temperature. The reference junction, T2, is at 71 °F. The voltmeter reads 18.743 mV.
