Expendable Thermocouple
1. Genenal
K type thermocouple is a sensor for temperature measurement. It can be connected to a fast potentiometer or a digital instrument to measure temperatures of melted iron, steed or other metals.
2. Specification
Type: Calibration no.: Composing Materials
+leg(1): -leg(2)
K: S: PtRh10% PT
K: B: PtRh30% PtRh6%
K: R: PtRh13% PT
