Dual Port Pressure Calibrator 36/3000PSIG

Reliable pressure calibration in the field
Used this on a mobile test rig and it held pressure no problem. Interface is simple and it boots up fast. Been through a few brands but Crystal gear always holds up. Highly recommend for field techs.

Great accuracy, rugged build
We tested this unit against a traceable standard and it was right on the dot. Housing feels rugged, good for outdoor work. Just wish the screen was a bit bigger - sometimes hard to read in direct sun. Still very satisfied.

Workhorse calibrator
We've used this model in the field for valve testing and it’s bang on. Pressure readings are fast and stable even in rough weather. Battery life is solid too. One of those tools you just trust after the first use.
