A Thermometer is an instrument designed to measure and indicate the temperature of a specific application or condition.
A Dial Thermometer (filled system thermometer) measures degrees celsius.
The standardized method is to place the unit in the shade to observe accurate readings
and not place the thermometer in the direct sunlight.
Hygrometers measure relative humidity in the air. (The % of water)
Accurate to within 3%. Humidity is measured in percentage; it compares the amount of moisture or water vapour
in the air. Relative humidity is measured on a scale of zero to 100 ; the higher the number the more moisture in the air.
