Temperature Calibration

Omega has a state-of-the-art Temperature Calibration Laboratory that uses a Sophisticated HVAC system to control both the temperature and humidity to precise limits. This ensures the best accuracy from the high precision measurement equipment used inside. The lab is built as a room within a room to eliminate temperature fluctuations from exterior walls and all high temperature furnaces are located outside the lab to ensure temperature and humidity stability inside the lab.

Omega uses a variety of fluid baths, furnaces, and calibrators to perform temperature calibrations over a wide temperature range. Each heat source is outfitted with an independent NIST traceable standard. The most accurate equipment is selected for each calibration situation to provide the lowest temperature measurement uncertainties.

Omega Calibrations offer the following:

• All NIST traceable
• All Meet or Exceed ISO10012-1, ANSI/NCSL Z540-1-1994 Standards
• Lab is ISO 9000-2015 compliant
• Low measurement uncertainties
• Individual Probe Calibration
• Instrument Calibration
• System Calibration (Probe connected to Instrument)
• Five Levels of Calibration Available
  (CAL-1, CAL-2, CAL-3, CAL-4, and CAL-5)

Omega’s temperature calibration lab has the resources to test from -112°F (-80°C) to 2372°F (1300°C).

Omega also has the capability of testing at the boiling point of Liquid Nitrogen, -320°F (-196°C). Maximum calibration temperature range is based upon probe configuration and useable length.

Minimum Probe Length for Calibration Purposes

Five Levels of Calibration Available

CAL-1

CAL-1 documents that the products you buy comply with Omega’s specifications. This calibration is normally FREE and gives you additional assurance that what you are buying is exactly what has been specified in the product specifications.

CAL-2

CAL-2 documents not only that the equipment you buy meets the published specification, but also that calibration and testing were performed using NIST-traceable equipment.

CAL-3

CAL-3 provides temperature deviation data at Omega’s pre-determined temperature points as well as a list of all test equipment used with calibrations traceable to NIST. This calibration is performed in accordance with ISO-10012-1 and ANSI/NCSL-Z540-1-1994 requirements. This certificate is available for most Omega manufactured thermocouple, RTD, and Thermistor temperature measurement probes.

Note: CAL-3 calibration data is given in °F standard, unless requested in °C. CAL-3 and CAL-4 also available on thermocouple wire and probes less than 178mm (7″). Standard Calibration points: 100°C (212°F), 150°C (302°F). and 200°C (392°F). Upper temperature value may be limited by wire insulation.

CAL-4

CAL-4 is similar to the CAL-3 except that specific temperature points are chosen by the customer. This calibration is also performed in accordance with ISO-10012-1 and ANSI/NCSL-Z540-1-1994 requirements. This certificate is available for most Omega manufactured thermocouple, RTD, and Thermistor temperature measurement probes.
