Fit-up Champagne 108mm

Precision barometer. Minimum hole size 87mm.

A Barometer is a Precision instrument. A barometer is a scientific instrument used to measure air pressure.

Pressure tendency can forecast short term changes in the weather.

Many measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries.

What is a barometer?

The barometer is an instrument for measuring atmospheric pressure, used especially in weather forecasting.

Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.

An aneroid barometer indicates pressure on a dial using a needle that is mechanically linked to a partially evacuated chamber, which responds to pressure changes.

It was invented in 1643 by the Italian scientist Evangelista Torricelli, who used a column of water in a tube 34 ft (10.4 m) long.

Fishermen are keen strategists using a barometer to determine fish behaviour trends.

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.
