Copper Point SPRT Model 108462
0°C to 1100°C
Isotech has a long history of making SPRTs to the Silver point (Model 96178) and this experience was combined with new research to produce the new copper point SPRT (Model 108462).
Gold / Platinum Thermocouple
0°C to 1000°C.
The most popular of the special thermocouples Isotech makes for researchers
Isotech Model 670 SPRT
-200°C to 670°C
The 670SQ is our latest thermometer, to be specifically designed to give optimum performance up to the aluminium point.
Isotech Model 96178 HTSPRT
0°C to 1000°C
This high-temperature thermometer is a significant contribution to better high-temperature calibration.
NPL Platinum / Palladium Thermocouple
0°C to 1600°C (R or S)
These Platinum / Palladium Thermocouples (Pt/Pd) are manufactured by the National Physical Laboratory (NPL) who have developed a novel physical mechanism which mitigates the mechanical stresses caused by the different thermal expansion of Pt and Pd wires.
Standard Thermocouple Model 1600
The type R and S standards will cover the range from 0°C to 1600°C.
The measuring assembly comprises a 7mm x 300mm or 600mm gas tight 99.7% recrystallized alumina sheath inside which is a 2.5mm diameter twin bore tube holding the thermocouple.
