Why Choose Custom?

Like any product that is custom-made, our custom calibration test benches and custom calibration trailers and containers are built to your company’s specifications.

Besides getting the test bench or calibration trailer/container that you need, there are many benefits, as well.


  • Saves you time! Allows users to test instrument prior to installation – all in one place!
  • Prevents possible safety hazards by performing motor or calibration checks prior to climbing scaffolding or going into a possible hazardous location.
  • Panel will allow users to test multiple pressure ranges with better accuracy at one station rather than pulling multiple pieces of equipment out to the field to perform test.
  • Every instrument on the bench is calibrated all in one place.
  • Controlled environment for performing testing of all safety and critical electrical equipment.
  • Some instruments must be calibrated using multiple instruments. With a custom bench, all these instruments are at your finger tips.
  • Impress auditors, visitors or possible customers at your shop by having a central location for calibration.
  • Improves overall shop cleanliness, organization and presentation.
  • Allows for accountability of test equipment by being mounted in panel. Your equipment cannot easily be removed.
  • Calibration trailers are designed for the way that YOU operate and the way that makes sense to your organization.
