Why is it importantto study the tools used for measuring weather

• It is important to study this because for some people like fishers they go out to the sea they should know what weather will come so that they know when to catch fishes

Thermometer

• Use to measure air temperature

• Units used by thermometer are

• Kelvin, Celsius, Fahrenheit

• Has a important part the temperature

Hygrometer

• Used for measuring relative humidity and

. Moisture content in the atmosphere

• Units used are Celcius and Fahrenheit usually

• The one who invented this is a German Lambert

Psychrometer

• Measures relative humidity in the atmosphere

• Through 2 thermometer dry bulb and wet bulb

Thermometer

Dry bulb is use to measure temperature exposed

By air

• Wet bulb is dipped through water then it is

Determinde by its sorrounding area

• The one who invented this is a German R. Assmann imgkid.com

Hair hygrometer

• Hair is hygroscopic

• Its length change may be magnified by a

mechanism and indicated on a dial or scale

• The one who invented this is a Swiss H.B.

Saussuro

Electric hygrometer

• Measures the change in electrical

resistance of a thin layer

• The one who reasearched this is a American

Dumore

Rain gauge

• Measures amount of precipitation

• The units used are inches and cm
