Pressure Calibration

Even the highest quality pressure instruments are subject to drift over time, resulting in inaccurate measurements and substandard performance. It is very important that all pressure instruments are calibrated frequently. Calibration intervals and error limits should be defined and records of the calibration results should be kept, maintaining instrument integrity. Neglecting calibration can result in unplanned production downtime, inferior products, or process quality issues. In addition, allowing pressure instruments that are critical to the process to drift out of specification could potentially result in a risk to employee safety. The cost of calibration is normally insignificant compared to the potential production or injury costs.

UniCal’s calibration laboratory uses high accuracy Deadweight Tester, Modular Pressure Controller/Indicator, Pressure Calibrator, Digital Pressure Gauge and Digital Manometer. All the calibrations are performed by comparison method.
