DuoTec BW Moisture Meter, ASTM F2659

DuoTec BW Moisture Meter, ASTM F2659

The DuoTec BW Moisture Meter is a cutting-edge device designed to accurately measure relative humidity (RH) in concrete floors, a crucial step in preventing mold growth and moisture-related damage to flooring. This meter not only adheres to the rigorous ASTM F2659 and ASTM F2170 standards but also offers a comprehensive solution for professionals in construction and flooring.

Understanding the Importance of RH Measurement Moisture in concrete slabs can lead to significant issues, including adhesive failures, blistering, and the growth of harmful mold. Surface-level moisture readings often don't tell the whole story. The DuoTec BW Moisture Meter, with its ability to measure RH throughout the concrete's depth, provides a complete and accurate moisture profile, ensuring long-term integrity of floor coverings and coatings.

How it Works: Precision and Efficiency The testing process involves drilling a 0.625in (16mm) borehole into the concrete to a specified depth. This borehole is then lined with a plastic sleeve, allowing the internal environment to reach temperature and moisture equilibrium. Once equilibrium is achieved, an RH BluePeg Probe is inserted and connected to the DuoTec BW Meter. This allows for periodic, precise measurements of humidity levels. A key advantage is that the probes are installed below the floor surface and covered with a cap between readings, meaning normal construction activities can continue uninterrupted.

Comprehensive Concrete Humidity Measurement Kits Lignomat's Concrete Humidity Measurement Kit is designed to meet all ASTM F2170 requirements, offering a complete set of equipment for reliable RH testing. Each kit is thoughtfully assembled to include:

• LignoTec RH Meter The heart of the system, capable of reading RH BluePeg probes and doubling as a non-invasive moisture meter.
• NIST-certified RH BluePeg Probe: Recoverable and reusable, ensuring cost-effectiveness and sustained accuracy.
• RH Adaptor: For connecting the probe directly to the meter for ambient temperature and humidity readings.
• RH Cable: Ensures secure and accurate data transmission.
• 10 Plastic Sleeves with Caps: For preparing multiple test sites efficiently.

These components are housed in a durable, foam-lined, hard plastic carrying case, ensuring protection and easy transport. For larger projects, additional probes and sleeves are available separately. Calibration Check Solutions are also offered to verify performance, along with brush and vacuum attachments for optimal borehole preparation.

DuoTec BW Meter: Versatility and Accuracy The DuoTec BW Meter stands out with its versatile functionality. Beyond reading RH BluePeg probes for ASTM F2170 tests, it also serves as a non-invasive moisture meter. This allows for quick, near-surface moisture level measurements on a relative scale, with selectable measuring depths of 0.25 and 0.75in (6 and 19mm) for various materials including concrete, gypsum, and wood, meeting ASTM F2659 standards.

Its large LCD display provides clear readings of relative humidity, temperature, dew point, and GPP (grains of water per pound of air) with an impressive 0.1 resolution across all ranges.

• Relative Humidity Accuracy:
  • ±2% for 10–90% RH
  • ±3% for 0–10% RH or greater than 90% RH
• Temperature Accuracy:
  • ±0.5° for 32°–120°F (0°–49°C)
  • ±1° from 5°–32°F (-15°–0°C) and from 120°–160°F (49°–71°C)

The meter can also function independently as a thermo-hygrometer for ambient conditions when used with the RH BluePeg Probe and Adaptor.
