Traceable Fridge/Freezer Digital Thermometer with Calibration; 5 mL Bottle Probe

We use these for work in the patient nutrition fridge in our clinics and they work pretty well. I've had no complaints, but YOU MUST KNOW THAT THEY DO HAVE AN EXPIRATION DATE.

Good lower cost thermometer, meets our needs for refrigerator monitoring. We have bought several of these thermometers in the past. The first one we received quit working after about 6 weeks. I was unable to return to Amazon because it was outside the 30 day return window. I reached out to Cole-Parmer, manufacturer and they sent me a new one.

Our inspectors and third party auditors loved it and the certificate of calibration is part of our HACCP plan. Used in a yeast chamber, aging cellar, walk in refrigeration unit, and vending machine to monitor conditions. We andjust our temperature sensors according to this unit which saves us the headache of calibrating and certifying all of them. Would buy it again when the certification expires.
