The WHIPMIX insulated Thermocouple #96312 is the OEM temperature sensor for the Pro200 Series porcelain furnaces — the Pro200 and the ProPress200. WHIPMIX specifies an upgraded Thermocouple on this generation for improved accuracy, and it is the component the controller reads on every firing, pressing and calibration cycle. Everything downstream — shade match, glaze, Press completeness, crystallisation of lithium disilicate — is only as honest as this sensor.
The Pro200 muffle is rated to 2200°F with quartz-tubing windings, so the sensor works in a genuinely punishing environment. This part is the insulated version specified for the Pro200 generation. It is not interchangeable with the Pro 100 Thermocouple (#96184), which is a different assembly on an earlier control platform.
Unlike the retired Pro 100, the Pro200 Series remains a current, supported WHIPMIX platform — so a Thermocouple swap is a routine service item, not a scavenger hunt. Keeping one on the shelf turns a dead furnace from a multi-day production stop into an afternoon.

When a Thermocouple Needs Replacing
Per the WHIPMIXPro200 Series Furnace Operator’s Manual, a Thermocouple Error is raised when the furnace detects an open Thermocouple for 25 seconds; the furnace automatically shuts off the heating elements. Power the unit off and back on to clear it — if the error returns, the Thermocouple should be replaced.
Other signals worth a sensor check before you blame the ceramic:
Shade drift across a whole day’s firings at settings that used to be reliable
Calibration that will not hold between ProCal checks, or repeated calibration failures
A muffle-test temperature reading that looks implausible against room temperature
Under-fired results, poor glaze, or incomplete presses with no other cause
A Max Temp Error alongside erratic temperature behaviour
Maintenance note from the factory manual: charcoal may be used in a purge cycle to clear muffle cross-contamination, but WHIPMIX warns it can shorten Thermocouple life. If your lab purges with charcoal, budget for the sensor as a wear item.
Recalibrate the furnace after any Thermocouple replacement. Calibration steps are reserved for certified technicians — WHIPMIX TOPS: 800-626-5651.
