The Tramex CM5, also known as the Concrete Moisture Encounter X5 (CMEX5), is a non-destructive digital moisture meter designed specifically for measuring the moisture content in concrete floors and slabs. It provides instant, precise measurements by detecting the electrical impedance of the material under test. This is done by transmitting a low-frequency electronic signal into the concrete through electrodes in the base of the instrument, where the strength of the signal reflects the amount of moisture present. The meter then converts this information into a quantitative moisture content value displayed digitally.
The Tramex CM5 offers multiple measurement modes. The primary mode is the non-destructive test (NDT) mode which offers moisture content measurements for concrete from 0 to 6.9% by weight. It also provides Carbide Method equivalent readings for concrete and other cementitious substrates such as gypsum and screeds, aiding consistency with standard industry testing methods ASTM F2170 and ASTM F2659. Beyond concrete, with optional probes, it can measure wood moisture content and relative humidity in materials.
In addition to moisture readings, the Tramex CM5 has a built-in hygrometer that measures ambient relative humidity, temperature, dew point, and humidity ratio (or mixing ratio), providing a comprehensive environmental profile. This is crucial in flooring and construction projects where ambient conditions affect material moisture levels. The device is compact, battery-powered (2 AA batteries), and features a clear digital display, making it highly portable and user-friendly for professionals assessing moisture levels in the field.
In summary, the Tramex CM5 measures moisture content in concrete and related materials non-destructively by electrical impedance, offers comparative industry-standard readings, and also measures environmental humidity parameters essential for moisture assessment in construction.
