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).
