1. Leakage Inspection Device/Leakage Detection Device Product Name: Leakage Detection Device

2. Leakage inspection instrument/leakage detection instrument Product model: RWS leakage detection instrument

3. Leakage inspection device/leakage detection device manufacturer: Ireland

RWS leakage detector: multi-mode leakage detector is used for nondestructive leakage detection and building leakage source search, including: house building, non-conductive one-sided search, repair and foam roof system, external insulation and finishing system (EIFS)

4. Overview of leakage inspection instrument/leakage detection instrument:

The multi-mode leakage detector is used for non-destructive leakage detection and building leakage source search, including:

Building construction

Non conductive single-sided search

Repair and foam roof system

External Insulation and Finishing System (EIFS)

The RWS leakage detector combines the functions and advantages of the first two humidity detectors, namely the Leak Seeker detector for testing roof leakage and the Wet Wall Detector for testing external insulation and finishing systems.

The RWS leakage detector adopts two operating modes: EIFS and Roofing. Each operating mode has two ranges, namely high and low, and can detect the leakage of the roof and its external insulation and repair system. The detection thickness can reach about 100mm.

5. Product features of leakage inspection instrument/leakage detector:

Leak detection for non-destructive roofing and external insulation and repair systems

Used to search for leakage sources

Easy to operate

Instant clear reading

The 'Hold' function makes it convenient for users to record readings

Lightweight design, battery powered

Compared with other non-destructive testing equipment, it is inexpensive and economical to use

6. Leakage inspection instrument/leakage detector roof leakage problem:

It is difficult or impossible to detect and locate leakage and corrosion inside and outside EIFS or Roofing systems through visual inspection, as under normal circumstances, these leakage and corrosion situations cannot be seen from the wall or roof surface. Leakage may be hidden and lurking deep in the base layer, walls, and roofs. If the above situation continues to exist, leakage will cause corrosion, destruction, and disintegration of the structure and other components. Similarly, the loss of heat value due to moisture insulation leads to the movement of heat within the building structure. Early detection of damp areas and appropriate repairs can reduce economic losses.

7. Working principle of leakage inspection instrument/leakage detector:

RWS leakage detector is an electronic handheld humidity detector that applies the principle of electrical impedance. During impedance testing, signals are transmitted between the electrodes, representing changes in impedance and converted into relative humidity readings, which are displayed in real-time on a large and clear analog dial.

The reading is real-time continuous reading, and the RWS leakage detector is also equipped with audio equipment. When the reading is large, it will give a sound signal.

The RWS leakage detector gives important information, which can be used to evaluate the moisture condition of most fiber EIFS wall coverings and roof systems, such as house building, non-conductive one-sided search, repair and foam roof. Low cost and easy to operate.

8. Methods for non-destructive identification of leakage sources using leakage inspection equipment/leakage detection equipment:

For EIFS, the RWS leakage detector detects and locates damp areas present in the waterproof cover layer, insulation layer, and base layer; For Roofing, the RWS leakage detector is used to detect areas of moisture in the middle layer, insulation materials, and inside or outside of the roof. The instrument is easy and fast to operate, with a lightweight design that allows for one handed operation. By detecting the damp area of the building, the leakage source can be traced and detected.
