Explaining the Ambient Humidity Range for UV222 Lamps' Optimal Operation
When the data sheet for the UV222 Industrial lamp states "Ambient Humidity: 5-90% RH", it means that the lamp works best in this relative humidity range.
Relative humidity (RH) is a percentage (0-100%) and is defined as the amount of water vapor in a volume of air relative to the maximum amount possible. This is because the amount of water vapor required to saturate a volume of air depends on the air temperature.
Simply put, the closer it is to zero, the drier the air. Conversely, the closer it is to 100%, the more saturated the air is with water vapor.
If the air is extremely dry (below 5%) or extremely humid (above 90%), there is a risk that the operation of the UV222 Industrial lamp will be affected.
