We recommend an annual calibration for all Preston Pressure Pitot Static Test units.
This ensures a long life for the unit, reliable functionality, and stable precision.

Factory calibrations are available with a typical turn-around time of 2-3 days.

All Preston Pressure products returned to us for calibration will undergo a leak diagnostics check. If any leaks are found over the factory permitted limit they will be fixed by us at no extra charge!

All units sent to us for calibration will also receive a free cleaning.

Prices:

• PS-625: $450

• PS-525, PS-500, PS-425: $350

• ALT and ASP digital indicators: $200 each

Prices do not include return shipping costs.

All Preston Pressure products returned to us for their annual calibration will receive a 10% DISCOUNT if they have been calibrated by us in the previous calendar year!
