Features: 1. Temperature memory, low voltage display function. 2. If there is no operation within 15 minutes, the machine will shut down automatically to save power. 3. If the sensor have fault, the display will show it. 4. The Fahrenheit and Celsius degrees display switch function. 5. Temperature measuring element with accuracy of 1%, high accuracy. Specification: Material: plastic, stainless steel Battery model: 1 * LR44 battery (Not included) Temperature measurement range: - 50℃ to + 300℃ (- 58℉ to + 572℉) Resolution: 1℃ Accuracy: -20℃ - 80℃) + / -1℃ Package list: 1 * Probe head 1 * Thermometer Operation instructions: 1. ON / 0FF: press this key to turn ON or off. The last measurement temperature will be displayed 1.5 seconds after starting up, and then the measurement mode will be entered. If there is no operation, the machine will shut down automatically after 15 minutes. 2. ℃ / ℉ : click this button to achieve Fahrenheit in temperature measurement mode, Celsius. Temperature measurement and low voltage display: if the voltage is lower than 1.3V LCD will display low voltage. E00 will be displayed when the sensor is broken or lower than the measurement range, and E11 will be displayed when the sensor is short circuit or the actual temperature is high and the measurement range. Temperature memory: The temperature measurement range of the BBQ food meat temperature tester is-50℃ to + 300℃ (- 58℉ to + 572℉). The digital thermometer has temperature memory and low voltage display functions. Automatic shutdown function: The digital thermometer probe is designed with an automatic shutdown function. If you do not operate within 15 minutes, the kitchen temperature gauge will automatically shut down to save power Fault display: The electronic kitchen temperature gauge with LCD, resolution of 1℃, if the digital thermometer probe is faulty, the display will show a fault Free switching of temperature unit: The temperature gauge has the function of free switching of temperature unit. You can switch between Fahrenheit and Celsius according to different environments or needs. Temperature measuring element accuracy 1%: digital thermometer has high temperature measuring accuracy, the internal temperature measuring element accuracy reaches 1%, and the data is accurate, which will help you make delicious food at the right temperature
