[quote=“mikemcbain, post:18, topic:911”]Thanks all for the information.
I did record Barometric Pressure from my local weather station for a year but could not find any relationship to my other Casino records so stopped. I did think maybe the air con in the Gaming room was having an effect and so I will follow up with your watch recommendation and try measuring at the table instead.
Lucky, no problems I have made some shocking posts after too much alcohol although I never drink when playing or play after drinking.[/quote]
What about the moisture in the air - degree of water in the air - humidity … ?
Humidity is normally measured as relative humidity (RH). RH is a percentage that indicates the amount of moisture in the air relative to the maximum amount the air can hold at that temperature. For instance, when air at a given temperature contains all the water vapour it can hold at that temperature, it has a RH of 100 per cent. If the humidity exceeds 100 per cent, moisture will begin to condense from the air. If the air contains only half the water it can hold at that temperature, the RH is 50 per cent.
Warm air can hold more moisture than cool air, so that the RH of a sample of air will change as the temperature changes, even though the actual amount of moisture in the sample air does not. For example, as a sample of air cools the RH rises.
Using Your Hygrometer
Your hygrometer will show the relative humidity (RH) in your house. Although the RH will not be exactly the same throughout your home, one hygrometer per house is usually sufficient. You should place it where the humidity symptoms are most obvious, in the room that you are most concerned about, or where your family spends the most time. Because hygrometers are small, they can be moved around in your house from time to time.
Don’t place your hygrometer near a radiator, a heat register or a chimney, or in any other location where it could be affected by direct heat.
Remember that a hygrometer does not produce instant results. It may take up to two hours to provide a stable reading in a new location or to adjust to sudden changes in relative humidity.
