Temperature Calibration

Thermometer, Pyrometer, Thermocouple Calibration and More

Temperature calibrationTemperature calibration for ovens, furnaces and temperature-reading instruments is performed by LTI Metrology at our Philadelphia, PA (USA) area lab and by field technicians for customers in PA, NJ, DE and some surrounding areas. These services are offered to meet all of your calibration needs including fast results with:

  • A2LA accreditation
  • ISO 17025 certification
  • NIST traceability

Fluke Equipment for Reliability

Top-of-the-line Fluke calibration equipment is used throughout the temperature calibration lab and for services performed in the field to verify optimal performance from your temperature instruments. The computerized equipment records all calibration readings, then we output the results from a database to ensure accurate reporting in our Calibration Certificates.

Scope of Temperature Calibration

Calibration of temperature-reading instruments and equipment is essential for ensuring accurate and consistent production and efficient use of energy. Our scope of calibration includes service for the following:

  • Portable temperature-reading instruments
  • Thermometer calibration for digital, infra-red, bimetal, surface and liquid in glass models
  • Dry-wells and liquid-baths with temperature ranges from -45° C to 700° C
  • Ovens and furnaces

Temperature Uniformity Surveys for Ovens and Furnaces

  • Uniformity surveys can be performed on-site
  • Calibration is according to AMS2750D pyrometry requirements
  • Technicians survey temperatures at various locations within the oven or furnace to accurately assess temperature consistency
  • Adjustments can be made as needed

LTI Metrology is the calibration lab at Laboratory Testing Inc. For convenience, we offer temperature calibration and all of our additional calibration services at a single location in Hatfield PA, not far from the Philadelphia area. Ovens, furnaces, temperature controllers and many other instruments can be calibrated right at your facility by our field technicians. You can count on reasonable turnaround with every order.

The Temperature Calibration Process

LTI Metrology utilizes a number of different processes to perform temperature calibration on a wide-range of instruments both in our lab and in the field. Digital recorder and thermometer calibration takes place on a Fluke multi-process calibrator that runs a Met/Cal software suite for multi-product Fluke calibration. This Fluke calibration system is first programmed with the appropriate inspection temperatures. Temperature readings are then taken from the test instruments and compared with the programmed output to determine their accuracy.

Pyrometer calibration, thermocouple calibration and some recorder and thermometer calibration are completed using dry-wells and liquid-baths with temperature ranges from -45° C to 700° C. The liquid in temperature baths and atmosphere in dry wells/blocks are set to a specific temperature for calibration. Once the appropriate temperature is reached, the test instrument and a standard are placed into the bath or well for a comparison of readings. Surface probes and thermometers are calibrated on special hot plates. Temperature calibration is usually a 5 point inspection, unless more inspection points are requested by the customer.
