Tramex CMEX2 Digital Concrete Moisture Meter for Floors and Screeds (0–6.9% MC, Non-Destructive, ASTM F2659)

Tramex Concrete Moisture Encounter X2 – Advanced Digital Moisture Meter for Concrete Floors

The Tramex Concrete Moisture Encounter X2 (CMEX2) is a cutting-edge, non-destructive digital moisture meter designed for concrete floors and slabs. It delivers fast, precise, and quantitative measurements of moisture content, using Gravimetric testing as a reference standard.

Accurate Moisture Assessment

The CMEX2 provides Carbide Method equivalent readings for concrete and other cement-based materials, along with comparative results compliant with ASTM F2659. With the addition of plug-in ports for the optional Hygro-i2® relative humidity probe (for ASTM F2170 testing) and optional pin-type wood probes, this instrument offers a comprehensive solution for flooring professionals seeking reliability and accuracy.

The Tramex Moisture Encounter CMEX2 is widely used by flooring installers, concrete contractors, and restoration professionals to assess moisture in concrete slabs before coatings or floor coverings are installed. The meter provides instant, non-destructive measurements up to about 6.9% moisture content in concrete and is commonly used during flooring inspection, concrete coating preparation, and water-damage remediation workflows, as described in the CMEX2 technical overview. :contentReference[oaicite:0]{index=0}

Professionals praise the CMEX2 for fast quantitative readings, a clear backlit digital display, and optional probes that expand testing to wood moisture and in-situ relative humidity measurements. These features allow the meter to support concrete moisture evaluation methods such as ASTM F2170 in-situ relative humidity testing, improving diagnostic capability compared with basic surface moisture meters, as explained in the CMEX2 product description and specifications. :contentReference[oaicite:1]{index=1}

Key Features

• Four measurement modes: Non-destructive moisture measurement, ambient hygrometer, optional external in-situ hygrometer, and optional wood pin probe.
• Five Non-Destructive Test (NDT) scales: Concrete %MC, CM Concrete (Carbide Method equivalent), CM Anhydrite/Gypsum, Gypsum Reference 0-12, and Reference scale.
• Provides instant readings to a depth of approximately 20mm (3⁄4") for accurate, repeatable results.
• Integrated Hygrometer probe measures Ambient Relative Humidity (%RH), temperature, dew point, and Humidity Ratio.
• Optional pin-probe mode measures wood moisture content from 5% to 30% with a comparative WME scale (7–100).
• Compatible with reusable Hygro-i2 ® probes for in-situ concrete testing per BS 8201, 8203, 5325, and ASTM F2170.
• Displays Relative Humidity, Temperature, Dew Point, and Humidity Ratio when using optional RH probes.
• Large, clear 2.3" x 1.4" (58mm x 35mm) digital display for easy reading.
• Front-lit display ensures visibility in low-light conditions.
• Bluetooth connectivity with iOS & Android apps for data integration and reporting.
• Hold function freezes readings, ideal for situations where meter display is not visible.
• Spring-loaded contact pins enhance signal penetration and compensate for uneven surfaces.
• Rugged, ergonomically designed enclosure for durability and comfort.

How It Works

The CMEX2 detects and evaluates moisture conditions in slabs or screeds by measuring electrical impedance non-destructively. A low-frequency electronic signal is sent through electrodes at the base of the meter. The signal strength varies with moisture levels, allowing the device to calculate moisture content in concrete and provide comparative values for other cementitious materials. Readings are clearly displayed on the large digital dial for easy interpretation.

Hygrometer Mode

When the optional Tramex Hygro-i2 ® relative humidity probe is connected, the CMEX2 switches to Hygrometer Mode. This enables in-situ RH testing of floor slabs per ASTM F2170 and BS 8201, 8203 Hood Method, along with ambient temperature, RH, dew point, and mixing ratio measurements. The probe is durable, reusable, and regularly calibratable.

Wood Pin-Probe Mode

By attaching the optional pin probe, the CMEX2 converts into a resistance-type pin meter for measuring moisture content in wood and wood-based products. It provides readings from 5% to 30%, and includes a species adjustment table and temperature correction chart for precise results across different wood densities and temperatures.

Additional Features

• Optional RH probe displays simultaneous readings for %RH, grains/lb or grams/kg, temperature, and dew point. Stainless steel probe is 2/5" (10mm) diameter and recalibratable (traceable to NIST and international standards).
• Supports sub-surface in-situ testing (ASTM F2170) and non-destructive hood method (ASTM F2420). Complies with BS 5325 and BS 8203 for above-surface RH readings.
• Ten-language interface: English, Spanish, French, German, Polish, Norwegian, Italian, Swedish, Dutch, and Portuguese.
• Hold function freezes readings on the digital display.
• Battery operated (supplied).

The Tramex Concrete Moisture Encounter X5 offers an enhanced non‑destructive quantitative evaluation of concrete moisture with extended functionality over the CMEX2, making it ideal for comprehensive slab and screed assessment in commercial flooring projects. For broader building envelope diagnostics — including wood, plaster, brick and drywall — the Tramex MRH III Moisture & Humidity Meter delivers reliable dual‑mode moisture and relative humidity measurements suitable for renovation and restoration workflows. When moisture inspection extends into composite structures such as marine hulls or sandwich panels, the Tramex Skipper 5 Boat Moisture Meter provides industry professionals with precision dual‑depth non‑destructive readings to help detect hidden moisture in GRP and similar materials
