General description The LCD Digital Temperature Meter is a compact and elegant device designed for precise temperature and humidity measurement. It features a clear LCD screen that displays readings in both Celsius and Fahrenheit, along with a time display function. This thermometer is equipped with dual probes, allowing for simultaneous measurement of indoor and outdoor temperatures, making it ideal for use in refrigerators, air conditioners, freezers, aquariums, and greenhouses. Technical specifications Temperature range: -50°C (-58°F) to +70°C (158°F) Accuracy: ±1℃ Resolution: >-20℃ corresponds to 0.1℃; ≤-20℃ corresponds to 1.0℃ Time display range: 1:00-12:59 Installation Open the battery cover and install a 1 7# battery, ensuring it is not installed in reverse. Usage Press the FSW function key to switch between Celsius and Fahrenheit. To set the time, press the FSW key to switch to time display, then use the HR key to set the hour and the MIN key to set the minutes. Place the internal probe (A) to measure the surrounding temperature and the external probe (B) where the temperature needs to be measured. Other information If the temperature exceeds 70°C (158°F), the display will show H°C (°F); if it falls below -50°C (-58°F), it will show L°C (°F). If the battery is low, the LCD will flash at a speed of 1 Hz, indicating that the battery needs to be replaced.
