I Product Features · Food temperature measurement range: -20--105/ · Product shell temperature resistance: above 300/ · The product uses 5.1BLE low-power Bluetooth master control, compatible with BLE4.2, the transmission distance is more than 30 meters-50 meters without obstruction, more than 10 meters through a load-bearing wall, more than 10 meters after the all-metal enclosed space is closed, and the transmission distance deviation under different ambient temperatures is no more than 20/. · The mobile phone can monitor the grilling process of six probes at the same time Multiple operation modes: recipes/target temperature/estimated cooking time · Stainless steel structure. USB charging, because the metal structure cannot be put into the microwave. · 20 minutes of fast charging can work compatible with more than six hours, it takes about 20 minutes to fully charge, and the green light on the base is on after full charge. compatible with probes that have not been used compatible with a long time, the battery protection IC is open circuit after the battery low voltage protection to ensure that there will be no battery problems if the battery is not charged compatible with more than 3 years. II Notes / compatible with some probes that have not been charged compatible with a long time, the red light will not go out after charging compatible with 20 minutes. At this time, the battery power must be at least 95/ and can be used compatible with about six hours. In order to protect the battery, the 5/ charge will be charged with a very small current, which may take a long time. Therefore, if the probe is not used compatible with a long time, it can be charged compatible with 20 minutes without charging. It is not necessary to charge it to 100/. The working time is not much different. The longest working time is about 8 hours when it is fully charged to 100/. The working time of 95/ can reach more than 6 hours. / Remove the probe from the charging station and insert it into the food. The insertion depth should exceed the safety line as much as possible; / Each grilling probe is independent of each other, and the grilling mode can be set compatible with each probe separately; / In the recipe setting function menu, the system has set 9 food processing temperature values, and their doneness levels have also been set. You can also set the recipe temperature yourself.
