Calibration Policy

This policy is applied to both our national and international customers for all instruments presently sold by DL Instruments.

DL Instruments recommends yearly calibration to maintain the instrument precision.

DL Instruments will calibrate all instruments currently manufactured. For discontinued products, an evaluation will be made on a case by case basis. Please call or Email before sending in the unit.

The cost to have a full calibration at DL Instruments ranges from $200-$350/unit depending on model number.

Turn-around time is usually less than 1 week (excluding shipping).

If during the calibration there is any minor repair (less than $150.00) needed to be done and the total calibration/repair cost is under $300.00 DL Instruments will automatically perform the repair work. But if the total cost exceeds $300.00, then you will be notified to make a decision to proceed or not.
