Tramex CMEX5: Non-Destructive, Quantitative Concrete Moisture Meter
The Tramex Concrete Moisture Encounter CMEX5 is the industry-leading non-destructive moisture meter engineered specifically for precise assessment of concrete slabs and cementitious screeds. Providing quantitative moisture content (%MC) readings (gravimetric-based, 0 – 6.9% MC), the CMEX5 enables flooring contractors and coatings applicators to confidently determine substrate readiness. Its rugged design, Bluetooth connectivity, and capability to integrate optional Hygro-i2 RH probes make it the essential tool for professional moisture diagnosis, risk reduction, and quality assurance on every concrete project.
Product Overview:
The Tramex CMEX5 is a professional-grade inspection tool that delivers immediate, dependable, and quantitative moisture data for concrete and gypsum substrates. Designed to prevent costly failures associated with excess moisture, the CMEX5 is crucial for pre-installation checks, quality control, and forensic investigation.
Key Features & Professional Advantages:
Quantitative Concrete % MC: Provides actual moisture content readings (0 – 6.9% MC), based on gravimetric standards, giving you verifiable, actionable data instead of simple comparative scales.
Non-Destructive Measurement: Utilizes high-frequency electronic impedance to measure concrete moisture down to approximately 20mm deep without the need for drilling, saving time and protecting finished slab surfaces.
Versatile Substrate Modes: Includes specific scales for concrete % MC, CM Equivalent Anhydrite/Concrete, and Gypsum floor screeds, covering the most common cementitious materials.
Future-Proof Expandability: Built-in capability to support optional accessories, including the Hygro-i2 RH Probe (for in-situ relative humidity testing) and Wood Pin Probes (for measuring wood % MC), extending the meter’s utility beyond non-destructive concrete scanning.
Professional Documentation:Bluetooth integration allows the meter to connect with the Tramex Meters App, enabling users to geo-tag readings, create moisture maps, log data, and generate comprehensive, audit-ready reports quickly on-site.
Job-Site Ready: Designed with a durable ABS body and spring-loaded contact pins for consistent results, ensuring reliability in commercial and industrial environments.
Ideal Applications:
Flooring Installation: Determine if concrete or screed slabs meet moisture requirements before laying down adhesives, vinyl, wood, or other coverings.
Protective Coatings: Verify slab dryness to prevent blistering, delamination, and failure of epoxies, urethanes, and other topical coatings.
Restoration & Remediation: Assess the severity and distribution of water damage in concrete structures post-flood or leak event.
Structural Inspection: Deliver quantitative moisture data for building condition reports, warranty verification, and defect analysis.
