Process Instrumentation Sales & Calibration has state-of-the-art hygrometer calibration facility on site. The calibration facility is traceable to NIST and NPL (National Physics Laboratory), U.K.
We produce our own very dry reference air (-90 °C dew point).
The calibration facility is designed to verify the dry air dew point produced by two independent systems. The first system is verified using accurate Mass Flow control supported by theoretical calculations and is finally verified by the MBW hygrometer. The Calibration System is used to generate precise, repeatable levels of water vapour in the calibration air.
The MKS Mass Flow Meter calibration is by CCR Process Products, certificate No. 8500M-07 which is traceable to NIST and accredited by SCC (Standard Council of Canada) to ISO-17025.
The PISC team has over 35 years of in-depth experience in hygrometer and instrument calibration. We have in-depth experience on the moisture probes performance evaluation and troubleshooting.
ISO:9001-2008 Certified, Certificate No. FM583896
We look forward to the opportunity of working with you.
