Non-drifting PtRh-Pt thermocouples

designs and manufactures high-end PtRh – Pt thermocouples. The patented design gives them outstanding properties in precision, lifetime and reliability.

A prominent feature is the use of different diameters of the thermocouple wires. As a result, the temperature-induced drift of the individual wires cancel each other out. The result is a thermocouple that will never drift!

ΔT New ΔT Year 1 ΔT Year 2 ΔT Year 3
Positive wire (PtRh10%) +0,0K +1,0K +1,5K +2,0K
Negative wire (Pt) +0,0K +5,0K +8,0K +10,0K
