Calibration

Calibration services for production, validation, and recertification programs

Thermometrics supports thermocouple and RTD calibration workflows for industrial, aerospace, semiconductor, heat-treat, and validation programs that need traceable measurement data, not just replacement sensors.

Calibration plans can be built around incoming verification, production release, in-process validation, periodic recertification, and drift tracking across large sensor populations.

For profile thermocouples, platinum RTDs, and specialty high-temperature assemblies, we align target points, tolerances, report format, and documentation with the way the sensors are actually used.

Traceable thermal verification for demanding sensor programs

The calibration workflow connects reference instrumentation, controlled temperature points, sensor identification, and repeatable reporting so engineering and quality teams can defend the measurement.

Calibration Range

-196 deg C to 1700 deg C (-321 deg F to 3092 deg F), including cryogenic and high-temperature applications.

Supported Sensors

Base metal and precious metal thermocouples, RTD probes, and complete RTD assemblies.

Calibration Methods

Fluidized bed systems, vacuum and inert gas furnace calibrations, plus specialized setups for demanding alloys.

Standards and Traceability

  • Calibrations performed to ASTM E220, ASTM E230, and AMS 2750 methods.
  • Results provided with NIST-traceable reference documentation.
  • Calibration reports available in multiple formats to support QA and audit workflows.

Typical Applications

  • Semiconductor wafer fab profiling thermocouples.
  • Mil-aero and critical heat-treat sensor calibration programs.
  • Advanced composites, pharmaceutical processing, and crystal growth controls.

Deliverables and Report Options

Calibration documentation can be configured to match your internal quality system and customer audit needs.

  • Point-by-point measured results with deviation data.
  • As-received and as-left reporting options for drift tracking.
  • Identification and traceability records aligned to your lot, PO, or asset scheme.

Program Support

For teams managing ongoing calibration demand, we also support recurring service models.

  • Batch calibration planning by sensor family, range, and criticality.
  • Combined calibration and sensor refurbishment workflows where applicable.
  • Service structures designed to reduce downtime and total lifecycle cost.

Fixed-Point Reference Coverage

Where the program calls for higher-confidence RTD reference work, fixed-point methods can be used to anchor calibration around well-defined temperature points.

  • TPW at 0.010 deg C, plus gallium, tin, zinc, aluminum, and copper reference points.
  • Useful for RTD work that needs stronger consistency across recurring calibration intervals.
  • Supports comparison against customer-required calibration points and tolerance schemes.

Expanded Instrument Coverage

Some calibration programs need more than probe-only verification, especially when the complete measurement loop has to be checked together.

  • RTD calibration approaches aligned to ITS-90, IPTS-68, and coefficient-based reporting models.
  • Meters, transmitters, and switch-oriented calibration support where the measurement chain must be verified together.
  • Thermistor and other specialty temperature-sensing devices reviewed as part of broader program support.
