MUL Multi-Use Thermocouples

MUL Multi-Use Thermocouples


Quantity: 50 Per Box

SYSCON Sensors MUL is an expendable, multi-use, non-splash and high precision thermocouple tip. It is suited for a wide range of molten metals - Iron, Steel, Copper, Bronze, and Aluminum. The MUL tip fits snugly on SYSCON Sensors TS-1 Handheld Digital Pyrometer.

The specially formulated, ceramic, non-splash sleeve is designed to eliminate splashing and resist slag adhesion, extending the number of dips. The aluminum foil on the cardboard tube adds extra protection and enables more readings per MUL, reducing overall cost. The unique combination of ceramic fiber, aluminum foil, and the high-density paper tube keeps the contact block and lead wire cooler.
