Pressure Calibration

We offer a full range of pressure and vacuum calibration services to ensure your gages perform well in industrial, medical, and scientific applications. Calibration is a process whereby technicians compare measurements taken from gages in your facility against those from factory-standard gages with known accuracy.

Routine calibration ensures that your gages are up to standard and within allowable tolerances. Regularly calibrating your equipment also results in improved workplace and employee safety along with better machine performance.

Pressure gages appear in factories, laboratories, and the field. Their high prevalence makes it easy to delay or overlook needed repairs, which can lead to equipment failure.

Several factors can cause a pressure gage to fail, including:

  • Vibration.
  • Temperature.
  • Mishandling.
  • Pressure spikes.

While some of these factors are endemic to a given application, others can be mitigated or corrected by trained technicians. At Instrumentation, we can calibrate equipment that handles up to 20,000 psi. We offer calibration services both on-site and in-house in our calibration lab, and we offer regional pickup and delivery for in-house projects. We perform most jobs within five working days from the time we receive your gage.


Although determining a proper calibration test schedule depends on many factors, most gages require more maintenance as frequency and intensity of use rise.

How do you know when to have your pressure gage calibrated? These steps may be helpful in deciding whether it’s time to schedule a calibration test:

  • Check the manufacturer’s recommended calibration interval: Equipment comes with a general estimate on how often it needs testing based on that tool’s application. If you use your pressure gages for more critical measurements, you may need to have more frequent calibrations.
  • Plan calibration before and after a significant critical measurement project: If you have a major project coming up, send your gages for calibration before using them on the job. Once finished, have them recalibrated again. Getting the same results after the test ensures your measurements are reliable.
  • Schedule a test after the instrument is damaged: Sometimes your pressure gages may not show signs of damage after impact or overload. Still, internal components may not function as intended, skewing your measurements.
  • Calibrate when customer or industry standards dictate: Depending on your industry and operations, you may need to have calibrated, certified pressure gages for taking measurements. If your client doesn’t explicitly state this parameter, check with your industry’s guidelines.


If your company takes critical measurements, you must schedule time for calibration of your pressure gages. Your business owns this equipment to take precise measurements of your products. Without reliable results, you risk sending out goods that fall short of customer expectations. Recalling and remaking those items increases production costs and impacts your brand’s reputation.

Instrumentation Ltd  Metrology is an expert in calibration, and our team can test pressure gages for clients in various fields. We’ve carried out calibration tests in many industries, including:

  • Breweries.
  • Food processing plants.
  • Petrochemical plants.
  • Oil refineries.
  • Scientific applications both in labs and in the field.
