Description
Jofra PTC Temperature Calibrator Repair
The Ametek Jofra PTC is a professional dry-block temperature calibrator — it heats and cools a metal insert block to precise, stable temperatures to calibrate temperature sensors (RTDs, thermocouples) in the field and lab. Its precision depends on the heating/cooling system, the temperature control and reference sensor, and (on reference models) the readout, which is where service focuses.
June Company repairs and calibrates the Jofra PTC for instrument-calibration and process teams.
Common Jofra PTC problems we fix
- Thermocouple-simulation / readout errors — the sensor-input or readout function reading wrong, repaired and recalibrated.
- Heating/cooling faults — won’t reach or hold the setpoint temperature, the heater/cooling system repaired.
- Reference-sensor drift — the control/reference sensor drifting, recalibrated against standards.
- Stability or uniformity out of spec — control-loop faults, corrected.
- Display or interface faults.
FAQs
My PTC won’t hold temperature or reads wrong — fixable? Yes. Heating/cooling and reference faults are repairable, then the control is recalibrated so block temperature is accurate and stable, with a NIST-traceable certificate.
Is stability verified? Yes — verified against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
