AlcoPro offers repair service on all Alco-Sensor models. Our factory-trained staff completes most repairs within two business days of receiving authorization. AlcoPro will also buy back your used Alco-Sensor or give you trade-in credit towards the purchase of a new Alco-Sensor or supplies. Send your used Alco-Sensor to us along with the Repair Authorization Form, and our staff will evaluate your Alco-Sensor and make you an offer. There is no charge for the evaluation, and no obligation to accept our offer.

  • No charge for repair estimates
  • No charge for trade-in evaluations
  • Factory replacement parts
  • Three-month warranty on repairs

We encourage customers to check out our Alco-Sensor Trouble Shooting page before sending an instrument for repair to ensure that the problem is not a low battery or some other simple issue that can be easily remedied without the need to send the instrument for repair.  Customers are welcome to call our Repair Department at 800 227-9890 if they are uncertain about the need to send their instrument for repair.


Please complete a Repair - Buy Back  Form and include it with your instrument. Click Here to download and print a copy of the Repair - Buy Back Form. Or you may call 800 227-9890 to request that we fax or mail the Repair Authorization Form to you.
