# Thermocouple Calibration Furnace – PTC

The PTC thermocouple calibration furnace is designed to provide a high stability portable heat source for the calibration of thermocouples using the comparison method. Standard features

- - 1200°C maximum operating temperature
  - High stability heat source with temperature range 400 to 1150°C
  - Accepts thermocouples up to 7.5mm diameter
  - Thermocouple is inserted & compared to the PTC 12/20's displayed temperature
  - PID temperature control & separate temperature display to 1.0°C resolution
  - The special work tube design provides better temperature uniformity than is typical for a furnace of this size
  - The metallic work tube is earthed for operator safety when testing metal sheathed mineral insulated mineral thermocouples
  - Rapid heat up and stabilisation makes it ideal for use in the laboratory or on site
  - Portable & self contained

*Options (specify these at time of order)*

- Factory calibration certificate stating the error between the workspace temperature & the displayed value at 700°C, 900°C, & 1100°C
- A UKAS traceable calibration certificate for customer defined setpoints is available
- A UKAS calibrated thermocouple is available
