Kolpak Thermometer-Kolpak Walk-In Cooler Thermometer Testing & Calibration

Your Kolpak walk-in cooler is a vital part of your commercial kitchen; not only does it keep food, drinks and other ingredients cold, but it also keeps them at a safe temperature. Because of this, it’s important to ensure that the thermometer on your walk-in cooler remains accurate, otherwise you could run into some serious issues.

Below are steps on how to properly test and calibrate a Kolpak walk-in cooler thermometer. This testing and calibration method is ideal for the MAC, Drop-In and Polar Pack Series of walk-in coolers. For a full overview, check out the video tutorial by our friends at Kolpak.

How to Test and Recalibrate a Kolpak Walk-In Cooler Thermometer



  • Step 1—Prepare a mixture of crushed ice and water in a cup or bowl to create a slush.

  • Step 2—Place the thermometer bulb into the slush and check the reading. The thermometer should reach 32° F. If the thermometer doesn’t reach 32° F, it will need to be recalibrated.

  • Step 3—If recalibration is needed, start by removing the face cover from the thermometer by gently prying it off with a flathead screwdriver or twisting it off.

    • NOTE: Take care when removing the cover so as to not damage it.



  • Step 4—Carefully hold the pointer as you insert a flathead screwdriver into the pointer slot. Slowly turn it clockwise for a lower temperature, or counter-clockwise for a higher temperature.

  • Step 5—Once the thermometer has been recalibrated to the appropriate temperature measurement, reinstall the thermometer cover gently.
