Monitoring humidity levels during restoration is crucial as it helps determine the extent of water damage and the effectiveness of the drying process. A thermohygrometer is specifically designed to measure both temperature and relative humidity, providing valuable data that can guide restoration efforts.

This instrument plays a vital role in identifying areas of high humidity that may hinder the drying process and can assist in making informed decisions about the ventilation and dehumidification strategies needed during water damage restoration. By keeping track of these levels, restoration professionals can ensure a drier environment, which is essential in preventing additional issues such as mold growth.

While a moisture meter is important for assessing moisture content in materials, it does not measure ambient humidity. An infrared camera can detect moisture within walls and ceilings but does not provide humidity readings. An air scrubber is used for air purification and removal of contaminants, not for monitoring humidity levels. Therefore, the thermohygrometer is the most suitable choice for this specific task.
