Furnaces include a complimentary box of Precision Temperature Control Rings (PTCR). A PTCR is a highly accurate ceramic temperature indicator which records the true heat treatment received by the fired product. They can be used as either a furnace calibration check or as a record of an individual firing. For a calibration check, fire the ring to 1500 C (or other temperature of interest) ramping at 120 C/hour during the last 200 C of the ramp, and then holding at that temperature for one hour. Compare the measured size of the fired ring to the chart to determine the actual soak temperature. Large differences (>10 C) between measured ring and program temperature indicate need for service or adjustment. A new thermocouple being a likely solution. To use the ring as a firing record, simply place a ring in the furnace along with your work and record its size as a permanent record of the heat treatment actually made in that firing. A PTCR is only good for a single use.
