Food temperature measurement range: -20 - 105℃ Temperature resistance of the product case: over 300℃ The product uses 5.1BLE low power Bluetooth master control, which is compatible with BLE4.2. Transmission distance: 30 meters to 50 meters without shielding, 10 meters through load-bearing space, transmission distance decreases by no more than 20% when passing through metal walls beyond 10 meters, subject to ambient temperature. The mobile phone can monitor the grilling process for six probes simultaneously Multiple operating modes: recipe/target temperature/estimated cooking time Stainless steel construction.

It takes about six hours for power to reach at least 95%. The remaining 5% of the battery will be charged at a very low current to protect the battery, which may take a long time. It is unnecessary to charge to 100%. The difference in working hours is not significant. Fully charged to 100%, the longest working time is about 8 hours. 95% charged can provide working time of more than 6 hours. Take out the probe from the charging seat and insert it into the food. The insertion depth should be beyond the safety line as far as possible. Each grill probe is independent of each other, and the grill mode can be set for each probe separately.
