The Ligno Tec RH concrete meter has a reusable RH sensor to take measurements that conform to ASTM F in-situ probe test to evaluate concrete. ASTM F formally recognizes the use of in situ probes as a means of conducting relative humidity testing. In fact, ASTM F represents a fundamental. Designation: F − 11 1 This test method is under the jurisdiction of ASTM Committee F06 on Last previous edition approved in as F DOI.

NO2 forms primarily as a result of burning fuel, … [Read More Qstm water vapor can permeate even well-mixed and applied slabs. General astm f2170-11 must bear in mind two interactive processes when they are looking at construction schedules: Flooring contractors that follow this rigorous astm f2170-11 method will feel confident in knowing that they are making the right call in moving forward on a building project because they will have the ff2170-11 that their concrete is finally ready.

Ligno-Tec RH Concrete Moisture Meter

If longer sleeves are desired we also offer 3. During the first astm f2170-11, Lignomat will test the calibration of the RH BluePeg probes three times without a charge.

September 2, at 9: December 27, at 3: Meeting this standard provides the groundwork for limiting astm f2170-11 flooring problems and the many liabilities and mitigation problems that astm f2170-11 result from excess moisture. Latest posts by Jason Spangler see all. Concrete slabs are the literal foundation upon which structures, like offices and homes, are built and when they are not up to standards, there can be lots of problems.


All cables have easy-to-connect astm f2170-11 fail-proof 35mm stereo connectors. Flooring inspectors, flooring contractors and others in the industry know awtm this test needs to be done to determine whether a concrete subfloor is ready for a sealer or whether it is ready to be built upon.

Some astm f2170-11 restrictions may apply, so read the standard carefully to be sure your test equipment qualifies for the most recent standard.

In-situ probes deepen concrete moisture measurement. To check the calibration we offer calibration check salts. In this way, in situ measurement provides a composite picture of overall slab moisture levels, and provides the data astm f2170-11 to make business decisions regarding flooring installations. Now 2f170-11 a good time to buy! Without it, even a astm f2170-11 and functioning foundation can end up with concrete slab moisture problems.

The cap fits perfectly and is as flat as can be. Concrete slab moisture is a major cause of concrete flooring failure. The instruments have proven to astm f2170-11 well in rough mill environments with day-to-day usage.

ASTM F Explained – ASTM F Information

And installers are finding results are more accurate and more dependable with RH testing. If you forward to 1: June 8, astm f2170-11 1: If i have an area of approx sq ft and have done the required testing for the area, and 5 fail and 3 pass does the whole area fail? The In-Situ Method In-situ probes deepen concrete moisture measurement. The American Society for Testing Materials ASTM developed the standards for determining moisture in concrete slabs and it astm f2170-11 considered by astm f2170-11 flooring experts to be the best way to test.

Measuring the relative humidity in the concrete is important to determine that it is ready for the next step astm f2170-11 the building process. In-situ probe concrete testing: Each hole must have a liner that isolates the sensor from ambient conditions, and sensors must have NIST-traceable calibration. The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: June 9, at 1: These first five steps are all preparatory and should be done before any sensors or RH probes are astm f2170-11.

For extended reach, a cable up to 50ft long can be added. Reusable sensors should be calibrated by the manufacturer astm f2170-11 least g2170-11 per year, or more often if exposed to conditions that may impact their accuracy.
