10 Best Tramex Moisture Meters 2026 in the United States

The Dec Scanner by Tramex is a non-destructive impedance moisture meter designed for efficient roof inspections. A significant strength is its compliance with ASTM D7954 standards, ensuring reliable performance. The solid-state circuitry and rugged molded body promise durability and long-term reliability, making it suitable for professional use over time.

Additionally, it features three ranges of sensitivity, allowing users to inspect various roof membranes and insulation thicknesses, which is particularly useful for diverse roof conditions. Its ergonomic control panel simplifies operation, making it user-friendly even for those who may not be tech-savvy. Moreover, it provides fast readings over large areas, saving significant time during inspections.

The fact that it operates safely without the need for regulatory restrictions or operating licenses is a notable advantage over nuclear meters. However, the scanner weighs 394 ounces, which might be cumbersome for some users to handle during extended periods of use. Additionally, it requires a 9V battery, which might need frequent replacements depending on usage. The Dec Scanner is a robust and efficient tool for professionals in roof inspection, offering reliable performance and ease of use with some considerations regarding its weight and battery requirements.

The Tramex Roof & Wall Moisture Scanner RWS is a pinless moisture meter specifically designed for measuring moisture conditions in walls and roofing systems. One of its main strengths is the non-destructive testing capability, which means you can measure moisture content without damaging the material. It features multi-mode functions that allow you to select depth penetration and sensitivity, making it highly versatile for different applications.

The Roof Mode is particularly effective for built-up and single-ply roofing systems, detecting moisture levels deep within the insulation and roofing layers. For walls, it is suitable for a variety of materials including EIFS, foam insulation, and other low-density constructions, helping pinpoint moisture issues accurately. The device is user-friendly, providing instant analog readings and comes with a telescopic handle for easier usage on roofs—ideal for contractors or inspectors who need reliable, quick results without complicated setup processes.

However, the display is an analog type, which might be less precise compared to digital displays. Additionally, the product dimensions and weight may make it slightly cumbersome to carry for extended periods. It operates on a single 9V battery, which is included. Thus, it suits professionals dealing with moisture inspections in construction and building maintenance. Despite its high functionality, its size and analog display are points to consider based on your specific needs.

The Tramex Concrete Moisture Encounter CMEX5 is a versatile, non-destructive moisture meter designed for use with wood, concrete, and other building materials. A key strength is its ability to provide instant and accurate moisture measurements using gravimetric testing as a baseline. It also offers a comprehensive range of material settings, including Anhydrite and Gypsum scales, allowing it to test up to a depth of 3/4 inch into concrete slabs. Users will appreciate the built-in hygrometer, which measures ambient relative humidity, temperature, dew point, and humidity ratio, helping to prevent moisture-related problems effectively.

The device's optional external probes enhance its functionality, enabling measurements of in-situ moisture content and the percentage moisture content of various building materials. Its Bluetooth connectivity for creating moisture maps, geotagging, and sharing reports adds convenience and utility. On the downside, the CMEX5 might be somewhat complex for those unfamiliar with advanced moisture meters, and its weight of 357 grams, though not excessive, could be a consideration for prolonged use. However, its durable and ergonomic design offsets this to some extent. This moisture meter suits professionals in construction and building maintenance who require precise and detailed moisture readings.
