OMEGA uses the different standards over varied temperature ranges to provide the highest quality and reliability on all of its calibration certificates. The standards for temperature calibrations are listed in the table below. The standard used depends on the probe being calibrated. OMEGA maintains all of these standards in-house to provide you with the quickest, most convenient and highest quality calibration available anywhere. Some of the standards we use for calibrations performed at our facilities are also available for purchase from OMEGA, for those wishing to do their own in-house calibrations. See Section K.

OMEGA can calibrate a probe by itself, an instrument by itself, or a probe connected to an instrument (system calibration). The pricing and temperature ranges listed below apply to most types of equipment; however, our product offering is so broad that you need to check with us for current pricing for a particular calibration. Be aware that there may be inherent limitations in a particular instrument that can limit the temperature range over which it can be calibrated.

† Probe must meet requirements based on calibration standards utilized as shown in table on previous page. *Prices are for new instruments and subject to change without notice. For recalibration, call customer service for price. Charges vary depending on the instrument being calibrated.
Note: Because of the large selection of temperature probes, thermocouple wire and instrumentation OMEGA offers, the pricing and calibration data points shown above are only an example and do not apply to every probe or system calibration. Contact OMEGA’s Customer Service prior to returning any instrument for calibration service.
Ordering Example: CAL-3, designate this calibration level when NIST traceability is required on the thermocouple probe or probe/instrument system you are purchasing new or returning previously purchased equipment for calibration, $110 (probe only), $135 (probe with instrument).
