Tec RH Meter with BluePeg Probe and Adapter

Tec RH Meter with BluePeg Probe and Adapter

The Tec RH Meter is a high-precision digital hygrometer designed for accurate measurement of relative humidity (RH), temperature, dew point, and grains per pound (GPP). It is specifically engineered to work seamlessly with BluePeg Probes, offering a comprehensive solution for concrete moisture testing in accordance with industry standards.

Key Features:

• Large LCD Display: Provides clear, simultaneous readings of relative humidity, temperature, dew point, and GPP with 0.1 resolution across all ranges.
• High Accuracy:
  • Relative Humidity: ±2% for 10-90% RH, and ±3% for 0-10% or >90% RH (for the probe and meter system).
  • Temperature: ±0.5°F for 32°-120°F (0°-49°C); ±1°F for 5°-32°F (-15°-0°C) and 120°-160°F (49°-71°C).
• Versatile Operation: Can be used with the included BluePeg Probe via a cable or directly with the adapter for ambient condition measurements, functioning independently as a thermo-hygrometer.
• ASTM F2170 Compliance: Fully meets the requirements for in-situ relative humidity testing of concrete slabs. This method is critical for preventing moisture-related damage to floor coverings and coatings, and for mitigating potential mold growth.
• BluePeg Probe System: NIST-certified probes are easily retrievable for repeated use, offering cost-effectiveness and efficiency.
• Durable Construction: Housed in a foam-lined, hard plastic carrying case for secure transport and protection of all components.

Importance of Concrete RH Measurement:

Accurate measurement of relative humidity transmission in concrete floors is paramount for construction and flooring professionals. Unlike surface moisture tests, the RH method provides a thorough profile of moisture content throughout the concrete slab's depth. This comprehensive data is crucial for:

• Preventing Mold Growth: High moisture levels in concrete can create an ideal environment for mold and mildew.
• Protecting Floor Coverings: Moisture can severely damage expensive floor coverings, adhesives, and coatings, leading to costly repairs and replacements.
• Ensuring Longevity: Proper moisture management contributes to the long-term integrity and performance of flooring systems.

How it Works (ASTM F2170 Method):

1. Borehole Drilling: A 0.625in (16mm) diameter borehole is drilled into the concrete slab to a specified depth (typically 40% of the slab thickness for drying from one side, or 20% from both sides).
2. Sleeve Insertion: A plastic sleeve is inserted into the borehole.
3. Equilibration Period: The boreholes are left to reach temperature and moisture equilibrium (typically 24 hours).
4. Probe Insertion & Measurement: A BluePeg Probe is inserted into the sleeve and connected to the Tec RH Meter for periodic, non-destructive measurements of humidity levels.
5. Protection: Between readings, the probes are protected with a cap, allowing normal construction activities to continue without interference.
