The CookPerfect Comfort Bluetooth Food Thermometer is another entry into the "smart" instrument category. This new genre of cooking tools is aimed at simplifying some of the tasks confronted during food preparation. The Comfort is designed to reduce the sensitivity of a thermometer to probe placement within the meat. This is accomplished by building several sensors into the probe, taking multiple readings of the internal temperature, and using the lowest value as the doneness indicator. The probe also has an ambient temperature sensor that detects the temperature inside the cooker. The internal and external sensors provide input to an algorithm that computes the estimated cooking time remaining.
The thermometer comes with the Bluetooth sending unit and one probe. The probe cable is 39" (1m) long, a bit short for easy outdoor barbecue use. Two batteries and a small screwdriver to remove the back cover come in the box as well. Installing the batteries requires a bit of dexterity as the screws are tiny.
The Bluetooth status and probe connectivity are indicated by LEDs on the sending unit. A flashing blue indicates the unit is on and searching for the app. A solid blue indicates Bluetooth connectivity. The probe status is indicated by a green LED. Slow flashing indicates the presence of a probe. Rapid green flashes indicate the temperature is within 5° of the target. Solid green means the food has reached the target. There are no numerical displays on the sending unit; everything quantitative must be done via the app. There is a magnet on the back to secure the unit to a metal surface.
The unit turns on when a probe is inserted into one of the two input ports. The sending unit then connects to the app via Bluetooth. The app displays two temperatures for each probe: the food's and the cooker's. (Actually, the readings of multiple sensors within the food are used, but the user only sees one.)
You can select a food type and doneness from a list of presets, or you can use a target temp of your own choosing. You can also set up to four time and four temperature alerts, as well as the target temperature, for each probe. You can set an alert if the cooker temp drops below or rises above your set limits.
After you've made your temperature and time settings, you press the "Start Cooking" button and the process begins. The core food temp and the cooker temp are used to calculate the time remaining before the food reaches the desired doneness. There is also a progress bar that indicates how far along the cook you've come, but no temp vs. time graph.
The unit's temperature accuracy may not be correctly represented with our testing protocol. While the numbers at 225°F and 325°F aren't encouraging (216°F and 342°F respectively), I can't think of any food that is cooked to those temperatures. This may be a moot point because the food end of the probe won't be used for ambient measurements anyway.
The user's manual provides only the minimum info needed to get started, but the company website has a number of helpful instructional videos. While probe placement in the food is not critical, there are a couple of caveats that are spelled out in the manual and on the videos. Care must be taken if grilling a flat piece of meat like a steak so that the cables aren't exposed to flames or excessively high temperatures. While the cables appear quite robust, there are a number of small gauge wires inside that might be susceptible to heat damage. Time will tell.
This product was conceived in Denmark and has that elegance that typifies Scandinavian design. In my tests, everything worked as intended. The app is easy to navigate and provides the needed functionality without unnecessary gilding. There is a contact function in the app to communicate with the manufacturer, but there is no explicit contact info in the manual or on the packaging. I didn't find any explicit warranty info, either. I couldn't find any info on purchasing additional probes.
This is a unique product, so it's hard to rate it against its competition. It's also at the high end of the price spectrum for a thermometer that comes with a single probe. I'd like to see more contact info and warranty information in the documentation. Nevertheless, it's an easy product to like. I'm giving it a Silver Medal.
