We grill a lot of fish in the summer, and lamb and beef during the winter. When grilling an expensive cut of meat, a Prime tenderloin for example, preserving the meat quality is imperative. A remote reading thermometer makes possible temperature monitoring while continuing to entertain guests. Here in Alaska, it’s also often more comfortable to be inside rather than outside.All of these devices measure the temperature at the tip of metal probes, and transmit that temperature information to a receiver via a radio-frequency link. This allows the user to remotely monitor the temperature at the probe tip.I researched these radio-frequency-based remote reading thermometers to replace a long-time device and chose the ThermoPro TP-20. After thoroughly reading directions, I inserted the enclosed batteries (very convenient), inserted the two temperature probes, and the sender and receiver established a radio-frequency link, with no need for my assistance. The two probes showed the same temperature probes provided the same temperature value, a quick check that the device was calibrated.I’ve not owned a dual probe remote thermometer before, but I used them both as I monitored the two ends of a 6-pound tenderloin. My family has rare-meat lovers and well-done lovers, and being able to monitor the thin and thick ends of the tenderloin allowed me to adjust the various heat sources on a gas grill. I usually use a charcoal grill and don’t have the ability to control the heating to this degree, but it’s still a useful piece of information. Of course I log the data, so the temperature differential will also be interesting to log. When planning a meal, it’s useful to know that a 6-pound tenderloin, cooked on gas, with the meat at this temperature and outside temperature at that value, will require 1:30 to cook.The manufacturer claims that the sender and receiver will communicate over a 300-ft maximum distance, a distance that I did not measure, but it certainly worked well through a 120-foot distance and through heavy plaster walls. I am very impressed with that performance.The receiver, the controller of the system, has pre-sets for FDA-approved cooking temperatures for a wide range of likely-to-be-grilled foods. Although I didn’t use the feature, the device also allows one to set other temperatures, instead. One can change from Fahrenheit to Celsius degrees, as well as access a timer and other features. Read the directions!Directions are easy to follow. The device was well-packaged, and included everything as advertised. It’s easy to use and provides accurate temperature information.My first use was for an almost-two-hour grilling of a tenderloin cooked over gas. I enthusiastically recommend this device.
