Wagner Electronics Rapid RH Installation Instructions

Installation Instructions

Step 1: Drill the Hole
Drill hole to the desired depth in concrete using a rotary-hammer drill and a ¾" SDS
drill bit*. Per ASTM F2170-02 standards, drill the hole to a depth of 1¾" (44 mm),
which is approximately 40% of the depth of a 4" (100 mm) concrete floor slab
poured on grade. For proper RAPID RH™ installation, be sure to position the
drill perpendicular (90˚) to the surface being tested. It is recommended that a drill
capable of approximately 750 rpm be used with the SDS drill bits.
For other slab thicknesses and drying conditions, please consult ASTM F2170-02
to determine the proper depth of the hole.
If the drill bit becomes extremely hot from
drilling several holes in rapid succession, allow
the bit to cool before drilling more holes.

T
he Rapid RH ™ moisture testing system
should be a part of the overall moisture testing
program on any project where moisture-sensitive
finishes are to be applied. Owners, General
Contractors, Flooring Contractors and Installers
need to be sure the tests they per form are
accurate, repeatable, and available to all who
want to know the current moisture condition of
a slab on their projects.
T
he Rapid RH ™ is a tool that significantly
improves the project team's ability to
instantly test and/or monitor the dr ying progress
of a concrete slab without adding substantial
cost to the project. The Rapid RH ™ enables
you to take periodic readings without having
to conduct other types of testing. The factor y-
calibrated "Smar t Sensors" using CMOS Sens ™
technology insures the sensor's accuracy and
fast equilibration.
Step 2: Clean the Hole
Use a vacuum cleaner, or dustpan and brush to sweep up the dust around the
hole. Attach the Rapid RH™ vacuum attachment to the straight extension of a
Shop-Vac vacuum cleaner hose. Insert the vacuum attachment into the hole and
vacuum the dust within.
Remove the vacuum cleaner extension from the hole and insert the special wire
bristle brush (provided with the kit) into the hole. Turn the brush several times to loosen
pulverized concrete from the walls of the hole. Vacuum again and repeat this step twice.

diameters vary.

may require 2 ½" - 1 ¼"
coupler depending on
vacuum model.
