Calibration Services for Measuring Instruments

JQA has offered calibration services since 1963. Initially limited to RF/microwave measuring instruments used to inspect electronic equipment and parts for export, these services were aimed at maintaining, stabilizing, and improving the performance of Japan's export products.

With the dissemination of the "traceability concept" in the latter half of the 1960s, JQA successively expanded its calibration services under the direction of the Electrotechnical Laboratory to include the microwave, x-ray, and laser fields.

In the field of length measurement, JQA received the guidance of the National Research Laboratory of Metrology and began offering calibration services for gauge blocks calipers, micrometers, and similar instruments in 1985. JQA's technology has won a reputation for excellence in this field.

In 1993, a new Japan Calibration Service System by Measurement Law was promulgated, with established the basis for a system to supply instrument standards. JQA was designated as the calibration organization at the time, and was put in charge of length, electromagnetic quantities, and standard reference materials(benzoic acid of calorimetric standards).

JQA also calibrates various measurement instruments for environmental monitoring associated with testing activities, including sound level meters, vibration level meters, analyzers for air pollution, particle counters and anemometers. JQA furthermore provides glass filters for calibrating spectrophotometers, standard micro scales, and other equipment.

As the above description indicated, JQA has a long history as the public organization that is intermediate between national standard and the standards of individual manufacturer and provides in a wide range of the fields.
