If the meter is recalibrated/repaired, the evaluation fee will be waived, or if prepaid, applied to the cost of the recalibration.

The meter over 20 years old may be traded-in on a new meter at a 10% discount, and the evaluation fee will also be waived.

If just the meter must be returned for repairs:

  1. The meter should be shipped in a carton approx 12"x12"x8"
  2. Carefully wrap the meter in several layers of foam padding
  3. Add sufficient additional cushioning to fill the carton
  4. Do not use spray foam.
    Spray foam can damage the meter, and it is also possible to "lose" a meter in a chunk of spray foam.


Our facility is not equipped to accept any package weighing in excess of 100 lbs.

Any delivery in excess of 100 lbs will be rejected.

Any freight delivery in excess of 70 lbs must arrive on a truck equipped with a lift gate and a pallet jack.


It is suggested that each AirData Multimeter, or HydroData Multimeter, be returned to the factory at least every two years for recalibration, maintenance, and software updates.

This will keep every meter up-to-date with ongoing improvements and new features as they are developed; and most importantly, continued maintenance will assure that each meter's original accuracy is maintained throughout the lifetime of that meter.

IMPORTANT: We do not calibrate instruments from other companies.


Turn-around time is about two weeks.

Rush handling is available for an additional charge. If you require RUSH HANDLING, please provide a completed Purchase Order that allows an option for repair time, and specifies that you need EXPEDITED handling.

If you wish to request RUSH Calibration Services, please contact Sales at 480-991-6744 before shipping the meter to Shortridge Instruments, Inc., so that this cost may be added to your Purchase Order prior to shipment.

An EXPEDITED CALIBRATION of less than two weeks may result in an additional fee.
