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.

The rate stated above does not including the shipping charge. However, DL Instruments does enjoy a discount shipping rate from UPS because of our large shipping volume. Both our national and international customers are encouraged to ship through our UPS account to get the discount rate.

Repair Policy  

This policy applied to both our national and international customers.

DL Instruments will perform repair work on all currently manufacturing models. Discontinued product evaluation will be made on a case by case basis. Please call or email before sending the unit in.

Repair cost varies with each unit, and is based on the model, part cost, and repair time. Based on past experience the average cost for a damaged unit is less than $300.

After you send your unit in, a preliminary diagnostic will be made by our engineers to evaluate the situation at cost of $100. The customer then will get a report on the unit and an estimation on how much is going to cost to repair the unit.

If you decide not to perform the repair work, then the unit will be sent back to you less the $100.00 diagnostics charge plus shipping.

If you decide to have the unit repaired at the quoted price, then the unit will be fixed and returned to you within 2 weeks (excluding shipping time).
