Digital LCD Temperature Meter Hygrometer Electronic Temperature Humidity Meter Weather Station Indoor Outdoor

Function:

• It can test the Temperature/Humidity of indoor/outdoor/aquarium/greenhouse planting area.
• Help improve the environment.

Related to Temperature and Humidity:

• The most pleasant indoor temperature and humidity for human's livingare:
• winter temperatureis 18 to 25°C, humidity is 30% to 80%; summer temperature is 23 to 28°C, humidity is 30% to 60%. More than 95% of people feel comfortable in this range.
• In an air-conditioned room, people will feel most comfortable when the room temperature is 19 to 24°C and the humidity is 40% to 50%.
• If considering the influence of temperature and humidity on people's thinking activities, the most suitable room temperature should be 18℃, and the humidity should be 40% to 60%
• Different living creatures pleasant temperature and humidity are different.

Operation method
1. Install the battery and the machine is ready to use.

2. Button function: [MODE] switch clock and alarm display mode/set current clock, alarm, 12 or 24 hour system, date; [ADJ] adjust the value of the set item; [MEMORY] display the highest & lowest temperature and humidity in memory Value/Clear the memory of the highest & lowest temperature humidity value; [℃/℉] Switch the temperature unit to display in ℃ (Celsius) or ℉ (Fahrenheit); [RESET] Clear all settings & memory values ​​and return to the initial state.

3. In the initial state, press and hold [MODE] for 2 seconds, the minutes and seconds of the current time start to flash, press [ADJ] to adjust the minutes and seconds, and press [MODE] continuously to set the "clock" and "12/24" respectively , "Month (M)", "Day (D)".

4. In the current clock mode (the two points between the clock and the minute flash once every second), press [MODE] once to switch the display to the alarm mode (the two points between the clock and the minute do not flash), press [ ADJ] You can switch the "Alarm" function/"Hourly Timekeeping" () function switch, and then press [MODE] for 2 seconds to set the alarm time and start the "Hourly Timekeeping" function, ( ) Symbol appears.

5. In the alarm mode, if there is no operation, it will automatically return to the current clock after one minute. At this time, press [ADJ] once to switch to calendar display, and automatically return to the current clock after 3 seconds. Press the [MEMORY] button to display the last temperature/humidity The maximum/minimum value since a CLEAR.

6. Press [MOEMORY] to display the maximum (MAX) and minimum (MIN) of temperature/humidity in memory, and press [MEMORY] for more than 2 seconds to clear the maximum/minimum.
7. F°/C° switch in the bracket
8. With 1.5m outdoor temperature probe

Precautions
1. If there is any defect in the machine, reinstall the battery;
2. After the battery is used up, please return it to the government designated place.
