Product Overview
The second-class standard platinum rhodium 10 platinum thermocouple is mainly used as a standard thermocouple for thermocouple calibration devices, as well as precision temperature measurement thermocouples used in laboratories.
Technical Specifications
Polarity: The positive electrode is made of platinum rhodium alloy wire (containing 90% platinum and 10% rhodium), and the negative electrode is made of pure platinum wire.
The resistance ratio of platinum wire at 100 ℃ and 0 ℃: R100/R0>1.3920
Wire diameter: ø 0.5mm
Total length approximately: 1025mm
Smooth spherical diameter at the working end: ø 1.2mm
When the measuring end temperature of the thermocouple is 1084.88 ℃ and the reference end temperature is 0 ℃, the thermoelectric potential should be 10.575 ± 0.030mmV
Stability of thermoelectric potential: not exceeding 5 μ v at 1084.00 ℃
Accuracy: not less than ± 1 ℃ (zinc point, antimony point, copper point three fixed points)
