A variety of equipment should be used to determine the scope of the water damage restoration project and monitor drying progress and environment conditions. Some types of equipments are listed below;
- Thermometers (i.e. air, surface contact, and infrared);
- Gas Detectors;
- Particle Counters;
- Moisture Meters;
- Thermal Imaging Cameras;
- Psychrometric charts and calculators;
- Data Logging Devices; and
- Remote Monitoring Systems
Thermometers measure the temperature of either the air of surface of a material.
Hygrometers measure the relative humidity of an air sample in a specific area. Relative humidity is the amount of moisture contained in a sample of air as compared tp the maximum amount the sample of contain at that temperature. This definition is accurate in concept; but strictly speaking, relative humidity is the ratio of the partial pressure of water in a sample of air to the water vapour pressure at saturation of that air at a given temperature and atmospheric pressure.
A psychrometer measure the difference in readings between two thermometers, one having wet bulb and other having a dry bulb, to determine the moisture content or relative humidity of air.
A manometer is an analog or digital meter that measures the static air pressure differential between two or more adjacent areas.
A Particle Counter is an instrument that detects and counts particles in the air and can differentiate particles bases upon sizes. Particle counting is based upon either light scattering or light obscuration of a particle as it passes through a detection chamber. An example of a particle counter measure from 0.3 of a micron to 20 microns; (a micron is one millionth of a metre).
A moisture sensor has penetrating pins used to indicate potential elevated moisture in various materials with an audible, visual signal or both.
Moisture meters are devices that display a value of moisture contents or level based on electrical variances in materials. They measure moisture either on a relative scale and referred to as moisture level; or in an actual percentage of moisture content. Two types of moisture meters are;
Non-Invasive meters; these meters use either electrical conductivity or radio frequency emissions to detect moisture in materials. This method allows measurements to be recorded without damaging the material.
Invasive meters; theses meters measure moisture based on electrical conductivity between two probes in the material being tested and displayed on a readout. This meter provides an actual percentage measurements of relative measurement. Meter attachments;
- Pin probes;
- insulated deep cavity probes;
- hammer probes with insulated pins; and
Thermal Imaging Cameras;
Thermal imaging cameras (infrared camera) are used to detect surface temperature difference and do not directly detect moisture or measure through materials. Thermal imaging cameras are useful to detect and show visual temperature differentials on material surfaces and more;
- an evaporative cooling effect on materials surfaces;
- missing or compacted insulation;
- thermal bridging; and
- air striking the surface of the material from the HVAC system.
