Concrete Humidity Measurement Kit with DuoTec BW Meter

Concrete Humidity Measurement Kit with DuoTec BW Meter

The Lignomat Concrete Humidity Measurement Kit with DuoTec BW Meter is an essential tool for preventing moisture-related issues in concrete floors. Excess moisture can lead to mold growth and damage to expensive floor coverings and coatings. This kit uses the relative humidity (RH) measurement method, providing a comprehensive moisture profile throughout the entire depth of the concrete slab, unlike surface-only measurements.

How it Works:

The process involves drilling a 0.625in (16mm) borehole into the concrete to a specified depth. This borehole is then lined with a plastic sleeve. After allowing the boreholes to reach temperature and moisture equilibrium (typically 24 hours), a BluePeg RH Probe is inserted. This probe is connected to the DuoTec BW Meter for periodic measurements of humidity levels. For convenience, probes are installed below the floor surface and covered with a cap between readings, ensuring minimal disruption to ongoing construction activities.

Key Features and Benefits:

• Comprehensive ASTM F2170 Compliance: Lignomat's Concrete Humidity Measurement Kits are designed to meet all requirements of ASTM F2170, the standard practice for determining relative humidity in concrete floor slabs using in-situ probes.
• NIST-Certified and Reusable Probes: The kit includes NIST-certified RH BluePeg Probes, which are easily recoverable and reusable upon completion of testing, offering significant cost savings and sustainability.
• Versatile DuoTec BW Meter: This advanced meter is central to the kit.
  • RH Probe Reading: It accurately reads the RH BluePeg probes for ASTM F2170 tests.
  • Non-Invasive Moisture Meter: The DuoTec BW Meter also functions as a non-invasive moisture meter, allowing for quick, near-surface moisture level assessments on a relative scale. It has selectable measuring depths of 0.25 and 0.75in (6 and 19mm) for concrete, gypsum, and wood materials, and meets ASTM F2659 for non-destructive moisture measurement.
  • Ambient Condition Measurement: When used with the RH BluePeg Probe and an included adaptor, the meter independently measures ambient temperature and humidity, making it a valuable thermo-hygrometer for environmental monitoring.
• User-Friendly Display: A large LCD provides clear readings of relative humidity, temperature, dew point, and GPP (grains of water per pound of air) with 0.1 resolution across all ranges.
• High Accuracy:
  • Relative Humidity: ±2% for 10–90%, and ±3% for 0–10% or greater than 90%.
  • Temperature: ±0.5° for 32°–120°F (0°–49°C), plus ±1° from 5°–32°F (-15°–0°C) and from 120°–160°F (49°–71°C).
• Complete Kit Contents: Everything you need for immediate testing is included in a foam-lined, hard plastic carrying case:
  • LignoTec RH Meter (DuoTec BW Meter)
  • One RH BluePeg Probe
  • RH Adapter (for ambient readings)
  • RH Cable (for probe connection)
  • Ten plastic Sleeves with Caps

Expand Your Testing Capabilities:

For larger projects or increased efficiency, additional BluePeg Probes and Sleeves are available separately. Lignomat also offers Calibration Check Solutions to verify probe performance, and specialized brush and vacuum attachments for optimal borehole cleaning and preparation.
