I use this thermometer to measure the temperature of beer while I work on draft beer systems. It's always proven to be reliable and accurate.

Just what I was looking for and exactly as described. The exact model that our health department uses to inspect restaurants.

The Comark PDT 300 is, in my opinion, the best thermometer for every day food service use. I am a former health department manager and I've used lots of models, but this one is rugged, reads quickly, is NSF approved and is very affordable.

This product works well and is easy to adjust and the FDA approves it and implements it as well. Great for your food processing business.

When turning on the thermometer, be sure to hold the on/off button for approximately 3-5 seconds. In the bottom right corner, you should see the C change to an F just before the actual temperature reading appears.

Use a coin to open the case. Replace with an (AB13) (1.5V LR44) battery and re-seat the case.

I would first check and make sure that the battery is installed correctly and not backwards. If it was installed backwards, that could prevent the backing to close completely. If the issue still persists, this may be a defective unit from the manufacturer.

Thanks for your question. The flashing "Lob" on your Comark PDT300 3" Digital Pocket Test Thermometer indicates a low battery. All you need to do is change the battery out and the flashing will stop.

With the unit in the off mode, depress the on/off switch and hold in until the "c" in the display switches to an "f". It will now measure in Fahrenheit.
How to calibrate the PDT300: 1. The PDT300 is only calibratable in a slush ice solution (60% crushed ice & 40% tap water) or a water bath. Do not attempt to calibrate in any other manner. 2. Immerse the stem of the thermometer to at least ½ length in the slush solution. 3. Wait for the reading to become stable (usually ± 2° of 32°F or ± 1° of 0°C). 4. Press & hold the D‐H button for 8 seconds to begin calibration. 5. CAL will be displayed for two seconds & calibration at 32°F/0°C is completed. 6. Remove the thermometer from the ice water & continue to take measurements. Note: CAL will be displayed anytime the D‐H key pressed for 8 seconds, but the thermometer will not be recalibrated unless the tip is inserted in cold water. You can also find these instruction int he "Learn More" tab: PDT300.pdf
