Product description Description Product features 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. The transmission distance is more than 30 meters to 50 meters without shielding, more than 10 meters through a load-bearing space for the transmission of 10 meters, after more than 10 meters delimited metal wall, transmission distance the ambient temperature is not more than 20%. The mobile phone can monitor the grilling process for six probes simultaneously Multiple operating modes: recipe/target temperature/estimated cooking time Stainless steel construction. USB charging, as the metal structure cannot be placed in the microwave. 20-minute quick charge can work for more than six hours, and it takes about 20 minutes to fully charge. The green light on the base will turn on after full charge Material: bamboo wood base, stainless steel probe Product size: 17.3 * 3.2 * Probem. things that need attention For some probes that have not been charged for a long time, the red light does not turn off after 20 minutes of charging. Currently, 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. Therefore, it does not need to recharge for 2 minutes, if it does not need to recharge for 2 minutes, for 2 minutes again. . It is unnecessary to charge to 100%. The difference in working hours is not significant. Full of 100%, longest working time is about 8 hours. 95% of the working time can be more than 6 hours. Take out the probe from the charging seat and insert it into the food. The insertion depth should be as far as possible beyond the safety line; Each grill probe is independent of each other, and the grill mode can be set for each probe separately ;In the recipe setting function menu, the cooking setting system has also set 9-type cooking and cooking level values. also set the temperature of the recipe yourself.
