Gauge Comparators


Pressure Gauge Calibration Standards


Transcat provides the equipment to serve as bench or field Pressure Gauge Calibration Standards. We offer gauge comparators, pump kits, and generation/testing sets to precisely calibrate pressure gauges, valves, transmitters, switches and sensors. Our gauge comparators are available in sets with a pump and manifold that allow for simultaneous connections of a test gauge and device under test. We’re your source for the top pressure calibration equipment, such as Ashcroft and Crystal Engineering comparators, Fluke reference gauges, Ralston Instruments test pumps, and other premier products.


The Right Pressure Calibration Solutions


What type of pressure gauge calibration equipment do you need? Determine if your equipment will be used in the field or a lab and check that accuracy specifications are sufficient for applications. Components should suit your DUT’s pressure measurement type, range and media. Depending upon the equipment, additional considerations include:


  • Maximum pressure generation
  • Vacuum ranges
  • Operating media (oil, water…)
  • Materials, dimensions and connections
  • Automated functionality


Pressure Generation and Testing Systems


The Crystal Engineering GaugecalHP pressure comparator is an ideal tool for calibrating low cost gauges that aren’t as strictly regulated by compliance standards. It works much faster than a deadweight tester and its portable, self-contained design allows for field or lab calibration.  Ralston Instruments makes a hand pump with 300 psi generation that allows for rapid, tool-free test gauge changes. A Yokogawa CA700 Pressure Calibrator Gauge delivers superior accuracy in the portable class. It is an automated unit with embedded processes for calibrating pressure transmitters and switches.


How to Calibrate a Pressure Gauge with a Gauge Comparator


Here is an interactive webinar from Transcat and Fluke Calibration that presents a step by step guide to the pre-test, testing, and post-test process for pressure gauge calibration, and ends with an overview of the types of calibration equipment needed for various measurement applications. See the presentation, transcript, slides and Q&A here: How to Calibrate a Pressure Gauge Using a Pressure Comparator


Buy Calibrated Gauge Comparators Only From Transcat


Because Transcat operates dozens of ISO 17025 Accredited Calibration Labs across the United States and Canada, we are uniquely positioned to offer new instrument calibration services on most of the items we distribute.  If your quality system requires that your instruments have a valid calibration certificate at all times, take advantage of our calibration services for gauge comparators so that your instrument arrives ready to be put into use.
