Only insert clean thermometers into the Tel-Tru Thermometer Calibrator opening.
- Wipe the stem of the thermometer before inserting it into the calibrator.
- Wipe the stem again before inserting the thermometer into any food product.
If it becomes necessary to clean foreign matter from inside the opening in the Tel-Tru Thermometer Calibrator, you may use cleaning brush(es) which are available to purchase on the Accessories page.
- Turn the unit off and allow it to cool to room temperature before proceeding.
- Insert the brush to full depth and rotate the brush as you remove it.
- Repeat this process several times until no matter is observed on the brush.
- You may dampen the brush slightly with a sanitizing fluid if you wish, but do not use more than enough to dampen the brush.
Clean the external surfaces of the calibrator with a damp cloth and mild detergent.
