All of our industrial pumps undergo Webtrol’s Quality Assurance Testing. So, in order to get accurate pressure readings, we use an NIST traceable calibrator on our pressure testing equipment. This certifies that the gauges and transducers we use in testing meet the National Institute of Standards and Technology (NIST) standards for accuracy.

The gauge is delicate and kept in its own metal case for protection. Fingerprints, dust, and even scratches on the weights can cause inaccurate results.

With NIST traceable calibration, any measurements taken with a certified device will have an unbroken chain of measurements that leads back to NIST maintained standards.

NIST is a non-regulatory federal agency founded in 1901 within the U.S. Commerce Department’s Technology Administration.
