J type Thermocouple The following J-type thermocouple chart shows across the temperature ranges that the spectrum of industrial applications that can be coupled to use handles. Maximum … The design of the SD4 thermocouple’s tip completely seals the sensor and provides 4 measuring points that can easily identify cold and hot zones. Temperature range: Thermocouples are best for working at high temperatures. The J type thermocouple has a generally more stable measurement range than the K-type thermocouple, since the temperatures it handles are generally medium. Vacuum, hydrogen or inert atmospheres. In contrast, some thermocouples can be used at up to 2500°C. 0.1°C accuracy in the following sizes: 30ga, 36ga, 40ga, 44ga. They are not subject to corrosion in moist atmospheres.
