Traceable to NIST

(U.S. National Institute of Standards and Technology)

LumaSense Technologies offers offers state-of-the-art calibration services for Infrared Thermometers, Radiometers, Optical Pyrometers, Thermal Imaging Systems at our Mikron product facility in Oakland, NJ.

The proliferation of high accuracy, infrared temperature measurement instrumentation and its growing application in critical industries, such as steel, glass, ceramics, aerospace, etc., has created the need for qualified primary calibration facilities independent of NIST.

To meet this need, Mikron has established a fully equipped and expertly staffed laboratory to perform calibration services to national standards on all makes of infrared and optical pyrometric temperature measurement and imaging equipment.

Mikron's calibration laboratory equipment has been certified by NIST and uses primary standard blackbody sources similar to NIST (freezing point of metal). Calibration procedures and specifications meet NIST standards.

Users of infrared thermometers, optical pyrometers, radiometers and thermal imaging systems can now get faster calibration service at less cost than previously available. Normal calibration time is less than 2 weeks from receipt of the instrument.

Primary, Secondary Calibration Sources
and Transfer Standards

Primary Calibration Sources

Freezing point blackbody sources provide fixed point primary temperature calibration standards, equal in precision to national standards. As such, they can be used to determine the accuracy of infrared thermometer standards, which are used in turn to calibrate variable temperature, wide aperture blackbody sources. These variable temperature blackbody sources are used in the routine calibration of infrared thermometers applied to process and research measurements. It is through this hierachy of traceability that the degree of uncertainty in everyday temperature measurements is determined.

Transfer Standards
 

Mikron can also supply customers with transfer standards which allow users to verify calibration at their own location. Transfer standards consist of special Mikron M190-TS infrared temperature measuring instruments which are accurately calibrated against the primary blackbody source and are contained in a specially designed case. These instruments are to be used only for calibration purposes, and should be returned to Mikron for checking at 12-month intervals.
