Moisture Determinations in Concrete Slabs 
The HC-3000 meter offers two operational modes for evaluating moisture conditions in buildings, noninvasive scan mode and relative humidity sensing with in-situ probes. This is a great tool for Concrete Contractors and Inspectors. Noninvasive Moisture Meter: For determining moisture conditions in solid building materials, the meter can be placed on a flat surface and it will instantly indicate moisture conditions on a digital scale. A unique feature allows the user to select between two measuring depths, surface to ¼" deep and deeper readings of ¾" deep. The feature allows measuring a dry surface over higher moisture deeper down. Relative Humidity and Temperature Meter: The RH BluePeg sensor can be used for measuring moisture evaporation from concrete slabs and other solid materials - even insulation. The sensor can be embedded into the material and it will absorb the evaporation from the material. Different relative humidity levels indicate more or less moisture coming from the concrete, which directly affects the floor covering or coating. The National Wood Flooring Association highly recommends the RH in-situ probe method for determining moisture in concrete slabs. Since the measuring area is below the surface the test results show if the core of the slab has dried out or if moisture is moving into the slab from the ground below. |
New iD-Intelligent Indicator for Concrete Compression Frames Now available on Concrete Compression frames from Humboldt, the new iD-Intelligent Indicator is soon to become the system of choice for those demanding accuracy, ease of operation, test documentation and dependability. The iD Indicator combines an accuracy that exceeds ASTM C39 and E4 requirements with a construction designed for the harshest of laboratory applications. Its 320 x 240 pixel screen aids in the indicator's user-friendly setup menu, while providing a bright easily readable display. During a test it simultaneously displays load, stress and rate of load in the time units selected. At the end of a test it automatically displays peak stress and load, and if activated, the average loading rate applied to the specimen during the test. Large alphanumeric characters display test data in any of the selectable engineering units, force units of lb, kN, kg and N, stress units of psi, MPa, kg/cm2, Kpa, size units of in, mm, cm, and time units of seconds or minutes. Its user friendly setup menu displays all menu option listings simultaneously, allowing the operator to quickly access the required option, and simply press a key to activate it or enter a numeric value to set the test parameter. This display feature eliminates the time consuming method of scrolling through single line menu displays to find an option or set a function. Its sample type menu lists six common specimen types to select from; cylinder, cube, beam third point and center point, cylinder split in tension and cross-sectional area. Just select and set. Test results can be automatically stored for hard copy documentation. |
