If the unit is no longer under warranty, regular repair charges will apply.

An estimate of the cost will be furnished before repairs begin unless the customer specifies otherwise.


If a meter is over 20 years old, and has not been returned to Shortridge Instruments, Inc. for service during the past two years, an evaluation fee of $75.00 will be required if the customer chooses to NOT have the meter repaired and recalibrated, OR if it is determined that the meter cannot be repaired.

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

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



The complete meter kit and all accessories should be returned to the factory for repairs and recalibration. Return the unit (in original carton and packing) to the factory, transportation prepaid.

The Repair Purchase Order and description of the problem should be enclosed in a packing slip on the outside of the shipping container.

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.


It is suggested that each AirData 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.

Shortridge Instruments, Inc. is proud to continue providing calibration and service support for ALL MODELS (previous and current) of the AirData Multimeter, HydroData Multimeter and FlowHood.
