That being said, I have heard a couple of different methods people are using.

10 Guidelines for ASTM F Compliance

These first five steps are all preparatory and should be done before any sensors or RH probes are installed. The MVER is defined as the rate of water vapor emissions from the surface of concrete and is determined with the use of a desiccant material sealed to the slab surface for a specified time period, then measured.

F170-11 has been believed that the change in the desiccant weight could be translated into a moisture ratio for the concrete beneath. At any time you can change from pin mode to scan mode by depressing up or down button.

Use up or down buttons to correct settings.

Sub-grade water vapor can permeate even well-mixed and applied slabs.

Section 9 of the standard requires that both the slab and the ambient air above it must be at service conditions for a minimum of 48 hours before testing. Now is a good time to buy! Use our checklist to record and report the RH readings.

Ligno-Tec RH Concrete Moisture Meter

During the first year, Lignomat will test the calibration of the RH BluePeg probes three times without a charge. It can be used for: Thanks for the question. The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Without studying pages and pages of operation manuals: October 27, at Lignomat has designed the RH BluePeg Probe, sleeves, cable and RH concrete moisture meter for a simple and fail-proof measuring procedure.

And moisture can still be an issue at grade so concrete foundations must be designed to include proper moisture drainage. If not, call their technical team and ask the questions. We have people who use the Rapid RH on shallow pours.

ASTM F Explained – ASTM F Information

June 8, at 1: Many contractors use vapor barriers directly under the slab to slow moisture permeation. Section asym of ASTM F details the requirements of each report, including test hole wstm, dates and times of measurements, RH reading, temperature reading, and any other conditions that might impact the RH reading see section 11 for complete reporting requirements.
