After the initial reading, readings can be updated at any time desired with two conditions in mind: The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Now is a good time to buy! That being said, I have heard a couple of different methods people are using.

Ligno-Tec RH Concrete Moisture Meter

Section 11 of ASTM F details the requirements of each report, including test hole location, dates and times of measurements, RH reading, temperature reading, and any other conditions that might impact the RH asgm see section 11 for complete reporting requirements.

To check the calibration we offer calibration check salts. Contact My Account 0 items October 27, at When concrete is mixed and poured, water vapor migrates from the bottom of the slab to the surface to evaporate.

January 9, at Ligno-VersaTecpin-pinless-RH, meter only. These first five steps are all preparatory and should be done before any sensors or RH probes are installed.

Check job site conditions. Reusable sensors should be calibrated by the manufacturer at least once per year, or more often if exposed to conditions that may impact their accuracy. Logically then, moisture levels at the bottom of a slab will read higher from those at the surface. As any professional knows, ASTM standards are established to help guide industry testing and also to help ensure standardized best practices to protect f2170-111 the installer and the consumer.

Be sure to familiarize yourself with ASTM F and choose the best concrete moisture test method for the job. Each hole must have a liner that isolates the sensor from ambient conditions, and sensors must have NIST-traceable calibration. We offer cost efficient, simple solutions to measure moisture.

10 Guidelines for ASTM F2170 Preparation and Testing

And installers qstm finding results are more accurate and more dependable with RH testing. We use cookies for shopping cart functionality, to personalize content and ads, to provide social media features and to analyze our traffic.

Many contractors use vapor barriers directly under the slab to slow moisture permeation.

The only thing we recommend is that you ensure that there is a good seal between the sensor body and the concrete wall. This website uses cookies. Your email address will not be published.

With all areas of ASTM-compliant RH testing, precision is key and data integrity must also be the focus for each flooring professional. Does the finish roof product have specifications astk testing the concrete deck? If not, call their technical team and ask the questions. Surface-based test results will fluctuate, even more, under these changes in environmental conditions.

For flooring and concrete professionals, ASTM F provides the standard for using relative humidity RH testing when measuring moisture content in concrete slabs. In this way, in situ measurement provides a composite picture of overall slab moisture levels, and provides the data necessary to make business decisions regarding flooring installations.

ASTM F Explained – ASTM F Information

If you forward to 1: This process requires time and quantifiable concrete moisture measurements to verify. While any professional must understand the exact requirements of standard F the most recent versionthe following are 10 guidelines to help ensure that you have met the criteria laid out in ASTM F The Ligno-Tec RH was designed for reliability and accuracy as well as sturdiness and ease of operation. ASTM F formally recognizes the use of in situ probes as a means of conducting relative humidity testing.

Can you please let me know your recommendation on this? I would verify that the hole depths are consistent and that environmental conditions are at service conditions. Each test hole must be drilled to the depth determined at Step 5 above section 10 of ASTM F and properly prepared.
