Temperature and Humidity Function: Digital display thermometer with temperature range from -50 degree Celsius to +70 degree Celsius and humidity range from 10 % to 90 % RH for direct display of temperature and humidity readings.
Time Function: The digital hygrometer has an alarm clock and calendar display (month and day) in addition to the basic time display. When the memory button is pressed, the memorised maximum and minimum temperature and humidity are displayed.
ALARM MODE: In the current clock mode (the two dots between the clock and the minutes flash once per second), the display will switch to alarm mode (the two dots between the clock and the minutes do not flash), press to switch to alarm mode.
SIMPLE DESIGN: The small stand on the back of the LCD thermometer allows the meter to stand on a tabletop for easy placement and portability. Requires only one #7 battery to operate and displays both indoor and outdoor temperature and humidity.
WIDELY USED: The digital thermometer can measure not only the temperature and humidity of your fish tank, but also outdoor and indoor temperature and humidity. You can put it anywhere for use.
【Two Installation Methods】Thermometer has a hole on the back to hang on the wall, and the bracket can be put down on the desktop. Only one 7 batteries can be used, while displaying the indoor and outdoor temperature, Celsius degrees Fahrenheit conversion function, and has a large value / small value of the recording function Measuring range: Indoor: -20℃～70℃, Outdoor: -50℃～70 Working voltage: 1.5V Display resolution: 0.1℃ Temperature degree: +/-1℃ Temperature Measurement Range: -50℃~70℃ Temperature Measurement Accuracy: Approx. ±1.0°C (1.8 oF) Temperature resolution: 0.1℃ (0.2 oF) Humidity measurement range: 10 % RH~90 % RH Humidity Measurement Accuracy: ±5%(30%-70%) ±7 Basic Function: Temperature/ humidity display ℃/ oF temperature switching display High / low temperature humidity memory function 12/24 hour clock Whole point chime function Daily alarm function Calendar display function Operation method: 1. Push open the battery door according to the direction indicated on the back of the machine, take out the battery spacer, and then put back the battery door, the machine can be used. 2. Key functions: (MODE) switch the clock and alarm display mode / set the current time, alarm, 12 or 24-hour system, date (ADJ) adjust the value of the set items; (MEMORY) display the memory of the high / low temperature and humidity value / clear the memory of the high / low temperature and humidity value; (℃ / oF) switch the temperature unit to ℃ (degrees Celsius) or oF (degrees Fahrenheit) to display; (RESET) clear all the settings / low temperature and humidity value. RESET) clears all set/memorised values and returns to the initial state. 3. In the initial state, press and hold (MODE) for 1 second, the minutes of the current time will start to flash, press (ADJ) to adjust the minutes, press (MODE) continuously to set the "Clock", "12/24", "Month (M)", "Month (M)", "Month (M)", "Month (M)", "Month (M)", "Month (M)", "Month (M)", "Month (M)", "Month (M)", "Day (D)". 4. In the current clock mode, (the two dots between the clock and the minute flash once per second) switch the display to alarm mode (the two dots between the clock and the minute do not flash), at this time, press (ADJ) can switch the "Alarm" (Alarm) function / "Whole time chime" (). At this time, press (ADJ) to switch between "Alarm" function/"Whole time chime" function, then press and hold (MODE) for 2 seconds to set the alarm time, and at the same time, start the "Whole time chime" function, and the ( ) symbol will appear. 5. In the alarm mode, if the operation is one minute after the automatic return to the current clock, then press once (ADJ) to switch to the calendar display, 3 seconds after the automatic return to the current clock according to the MAX/MIN button, the display of temperature / humidity after the second clear (CLEAR) since the big value. 6. Press (MEMORY) can display the memory of the temperature / humidity large value (MAX) and small value (MIN), press and hold (MEMORY) for more than 2 seconds to clear the memory of the large / small value.
