Dew point monitoring
Dew point is the temperature at which water vapour in the air starts condensing on the equipment. Environments with high relative humidity (RH) and rapid changes in temperature are most likely to experience condensing humidity. Dew point is always expressed as a temperature (°C).
The importance of dew point monitoring
In an unmonitored room containing several air conditioning (AC) units, it is possible to have half the room's cooling units adding humidity while the other half work to reduce it. This condition is known as demand contention and is one of the primary causes of excessive energy consumption in IT environments.
By monitoring and controlling dew point and relative humidity (RH) greatly reduces the frequency of demand contention. This is due to the fact that as air increases in temperature in an IT environment its dew point stays the same.
Most air cooling units simply maintain humidity based on the actual amount of water required in each pound of air that passes through the unit. Elimination of demand contention can significantly increase the efficiency of the cooling system and save excessive usage of power and fluctuation.
Dew point calculator
RH and air temperature are always related for any specific dew point temperature. If the RH and temperature are known a calculation can be made to present the dew point.
To check your dew point if you know your humidity and temperature use Spook's free dew point calculator below.
No existing monitoring?
Spook will work with you to identify what your monitoring needs are, secure the required hardware and install it. With nearly 20 years in the industry Spook is one of the leading experts in all things monitoring and are always expanding existing solutions to cater for each individual requirement and challenge it brings.Wireless dew point monitoring
We have installed Computer Room Air Conditioning units to ensure air cooling redundancy and to help compensate each other when a unit becomes stressed or less efficient. We found monitoring dew point to be a helpful measurement in order to reduce ‘demand contention’. OmniWatch checks dew point as well as keeping an eye on temperature, this helps ensure our server room is energy efficient.

Observing dew point
Have you ever drank a glass of ice cold water on a warm day and noticed water droplets collect on the outside of the glass? or have you ever been traveling in a warm car on a very cold day and seen condensation on the inside of the windows or windshield? Then you have definitely observed dew point.
Dew point and meteorology
Dew point helps meteorologists predict the height of the base of certain types of clouds together with calculating the percentage chance of precipitation. Meteorologists study dew point when checking how moist the air is as relying purely on relative humidity can be misleading.
Dew point can assist in forecasting overnight low temperatures too. In the majority of cases, the low temperature will not fall too far below the preceding evening's dew point. As temperatures fall towards the dew point, enough heat is released into the atmosphere to cause condensation.
