Gauge Certification
Certification insures accuracy and is necessary for certain types of testing. Certification is normally done on an annual basis. Certified Pressure gauge calibration is a process of comparing a gauge in at least 5 test points over the span to a known certified and traceable pressure measuring device. NNI can test and certify gauges with a calibration sticker and a N.I.S.T. (National Institute of Standards and Technology) calibration document.
