How it Works

1. Return all of your equipment

We recommend you return your complete SDT KIT, and that you send your equipment in its original storage case to prevent damage during transit. This also allows for accurate accounting of the received components, and to avoid additional costs upon return shipment.

*For TankTest systems, do not send the mechanical sleeve, the suction or discharge pipes.

2. Verification of Equipment

SDT Authorized Repair Centers verify every item/component received, including:

  • Ultrasound Receiver
  • Battery & Charger
  • Cables
  • Sensors & Accessories
  • Ultrasound Transmitters

3. Written Estimate for Repair/Calibration

A repair and/or calibration estimate is always sent for approval prior to completing any work. Please allow approximately three business days to receive our estimate from the time our repair center receives your SDT kit.

4. Work Completion and Return Shipping

Please allow approximately three business days from receipt of your order for our service center to complete your repairs/calibration.

Once completed and shipped an email notification will be sent with the shipping details and tracking number.

*For TankTest systems, allow an additional two days if the sensors need replacement.

SDT defines repairs as, “refurbishing and returning your SDT products to factory settings and performance levels.”

If your device is up-to-date in terms of its annual calibration, it is covered by SDT’s Lifetime Warranty, and all repairs are free*.
