Digital Thermometer

Digital ThermometerThere are many varieties of thermometers. I want to tell you about the digital thermometer-hygrometer. It gathers weather related data such as outdoor and indoor temperatures. You can also measure temperatures of liquids using a retractable probe. With the help of the inbuilt sensor the device can measure relative humidity indoors. The information on the current weather and on how it is changing is shown on a large LCD display. It is regularly updated based on the readings. The device also has a quartz clock (showing hours, minutes and seconds) as well as an automatic calendar. To turn on the thermometer insert the AAA battery that comes with the device. It is important that you observe the polarity. You can place the device on a table using the stand. You can also hang it with the help of a small nail. To measure outdoor temperatures use the remote sensor. The sensor can be placed outside the window with the help of the 3m cord. To set the current time and date, keep the "set" button pressed for 5 seconds. The values being set will start blinking. Using the "+" and "-" buttons set the current date and time in the following order: the year, the month, the day, then hours and minutes. To confirm the settings press "set". Your settings will be saved. The value displayed on the very top of the display is the outdoor temperature. The indoor temperature and the relative humidity are right below. Time and date are displayed at the bottom. The device can memorise maximum and minimum temperature and relative humidity values. It also saves the date when they were recorded. Thus, when you wake up in the morning, you will know if there were frosts last night. To see the maximum outdoor temperature on the LCD display, press the "out temp min/max mem" button 1 time.To see the minimum outdoor temperature press the same button one more time. To erase the saved values press the "memory reset" button. There are specialised sensors in the device designed to monitor the trends of temperature changes. If the temperature changes by 1 degree within an hour, a corresponding arrow will appear on the display. The up arrow means the temperature is rising; the down arrow means it's falling.We hope that this simple and easy to use device will help you choose the right clothes for the current weather.
