RH is the Ne Plus Ultra of Moisture Measurement

When determining the extent of water damage, a key indicator is relative humidity, or RH, which is the ratio of the amount of water vapor in the air to the amount of water vapor that the air can hold at a given temperature. It's measured as a percentage. RH is pivotal in gauging moisture levels and assessing the risk of mold and mildew growth.

Advantages of RH as a Moisture Indicator

• Accurate and Reliable: RH provides a precise quantification of moisture levels, reflecting the actual amount of water vapor in the air.
• Informative: RH values can provide valuable insights into the severity of water damage, enabling swift and appropriate remedial actions.
• Predictive: By monitoring RH fluctuations, potential moisture issues can be anticipated and preventative measures can be implemented to prevent mold or mildew from developing.
• Versatile: RH measurements can be conducted in various settings, from residential and commercial buildings to industrial environments.

How RH is Effectively Measured

• Psychrometers: These devices utilize wet and dry bulb thermometers to determine RH accurately.
• Capacitive Sensors: These sensors measure changes in the capacitance of a moisture-sensitive material, which are directly proportional to RH.
• Infrared Sensors: Non-contact, infrared sensors measure the absorption of infrared radiation by water vapor in the air, providing real-time RH data.

RH Levels and Interpretation

• RH below 40%: Dry conditions, at risk for static electricity buildup, and potentially damaging to wood and paper.
• RH between 40% and 60%: Ideal for most indoor environments, minimizing the growth of mold and mildew.
• RH above 60%: High humidity levels, creating favorable conditions for mold and mildew growth.

Conclusion

RH is an invaluable parameter for moisture measurement, providing essential information for assessing water damage and preventing mold growth. Its precise and reliable nature makes it the optimal choice for a wide range of applications, enabling effective moisture control.
