The Concrete Humidity Measurement Kit is equipped with the Tec RH Meter to read the RH BluePeg Probes using the provided cable or adaptor. The meter features a large LCD display that indicates relative humidity, temperature, dew point and GPP (weight in grains of water per pound of air) with 0.1 resolution for all ranges. Relative humidity accuracy for probe and meter system is ±2% for 10-90%, and ±3% for 0-10% or greater than 90%. Temperature accuracy is ±0.5° for 32° to 120°F, plus ±1° from 5° to 32°F and from 120°F to 160°F. The Tec RH Meter also functions independently as a thermo-hygrometer to measure ambient conditions, and is also available separately with an adaptor and one BluePeg Probe.
Measurement of relative humidity transmission in concrete floors can prevent mold growth and future moisture damage to expensive floor coverings and coatings. Relative Humidity (RH) measurement provides a complete profile of moisture content throughout the depth of the concrete slab, not just the surface.
A 0.625in (16mm) borehole is drilled in the concrete to the specified depth and lined with a plastic sleeve. The boreholes are allowed to reach temperature and moisture equilibrium, then a probe is inserted and connected to an electronic meter for periodic measurement of humidity levels. Probes are installed below the floor surface and covered with a cap between readings, and therefore do not interfere with normal construction activities.
Concrete Humidity Measurement Kits by Lignomat meet ASTM F2170 requirements, and provide a complete set of equipment needed for Relative Humidity (RH) testing. NIST-certified RH BluePeg Probes are easily recovered at completion of testing for reuse. Each kit includes a Relative Humidity Meter with cable, one BluePeg RH Probe, and ten plastic sleeves with caps. An RH Adaptor is provided to connect the probe directly to the meter for ambient temperature and humidity readings. Components are contained within a foam-lined, hard plastic carrying case. Additional Probes and Sleeves are available separately for increased efficiency when testing larger areas, Calibration Check Solutions for checking performance, and brush and vacuum attachments for borehole cleaning and preparation.
