- Tramex Meter Gauge
Used for structural analysis, the Tramex is a non-destructive meter. The meter produces an x-ray of the foundation condition, and provides an opportunity to scan roofing, walls, and the building envelope for excess moisture.
- Troxler Nuclear Density Moisture Gauge
ABB Testing uses a Troxler Nuclear Density Gauge to measure moisture. The Troxler Gauge is primarily used to detect leaks throughout the building envelope. This non-destructive test measures moisture by gauging the number of thermalized neutrons. The neutron source and detector are inside the gauge, which is placed directly above the test material surface. The fast neutrons enter the material (usually a roof or exterior wall element) and slow after colliding with hydrogen. The slow (thermalized) neutrons are counted and determine the amount of moisture under the material surface.
