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

The cost to have a full calibration ranges from $200-$300/unit depending on the model number.

Turn-around time is one week (excluding shipping time).

If during the calibration there is any repair needed to be done the customer will be notified to make a decision as to how to proceed.

The rate stated above does not including the shipping charge.

The customer can either get paid for the unit or use the proceeds as credit towards a new purchase.

The Buy Back procedure:

  1. Notify DL Instruments by either sending an email or calling.
    Please provide the serial number(s) of the unit(s) for sale.
  2. DL Instruments will provide the shipping address and instruction to ensure the units safe arrival.

Repair Policy

This policy applied to both our national and international customers.

DL Instruments will perform repair work on all models which are currently for sale. Discontinued products will be evaluated 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, parts cost, and the time cost to do the repair work. Based on past experience the average cost for one unit is about $300.

After receiving the units our customers send in, a preliminary diagnostic will be made by our engineers to evaluate the situation at cost of $100. The customer then will get a detailed report on what went wrong and what would be the cost to repair the unit.

If our customers decide not to perform the repair work, the units will be sent back to our customers charging $100.00 diagnostics fee plus shipping.

If our customers decide to have the units repaired at the quoted price, the units will be fixed and returned to our customers within 1 week (excluding shipping time).
