Thermocouple material is normally supplied to meet tolerances above 0C (32F). If material is required to meet
tolerances below 0C (32F), the purchase order must so state. Special selection of material is required.
Suggested initial calibration tolerance. Requirements should be discussed between purchaser and supplier.
Copper vs. copper can be used as an extension for Type B thermocouples if the transition is below 100C (212F).
Above 100C (212F), PCLW30-6 alloy should be used as the positive extension wire.
