Unlike competitor devices that can only withstand continuous exposure for 1 hour, the probe that is included with the K-Mometer can be left in the oven or grill for up to 24 hours.
Typically most meats that need to be slow-cooked in the oven or grill have a maximum cook time of 8 hours, with the exception of some smoked BBQ meats like brisket, which have to be cooked for 12-20 hours with the finishing temp between 190 and 205 degrees Fahrenheit. Here's a good resource for smoking different kinds of meat: http://www.smokedbbqsource.com/smoking-times-temperatures/
This version of the K-Mometer supports one probe, but in the future we may add support for multiple probes. The mobile app does support multiple K-Mometers if multiple temperatures need to be monitored.
When thinking about accuracy, it makes sense to think of it as "system accuracy". The probe and the
K-Mometer work as a unit, and this provides a certain level of accuracy in the readings. After performing 2-point calibration (at 0 degrees C and 100 degrees C), the K-Mometer can provide accurate readings of +/- 0.5 degrees Fahrenheit.

The K-Mometer can operate continuously for up to 18 hours on a single full charge of its internal rechargeable battery. If a longer continuous operating duration is required, an external USB power source can be used to power the K-Mometer as well as charge it at the same time.
