We repair most Alco-Sensor instruments. Our factory-trained engineers have most repairs completed within two business days of receiving authorization.  

Here's what you can expect from our repair and trade-in services:

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

Check out the Alco-Sensor Trouble Shooting page before sending an instrument for repair.  Or contact the repair department at 800.227.9890 or if you are uncertain about the need for repairs.

We will also buy back your used Alco-Sensor with cash or a trade-in credit towards a new Alco-Sensor or supplies. Fill out and send the Repair / Buy Back Form along with your Alco-Sensor. There is no charge for the evaluation, and no obligation to accept our offer.
