Measuring Rh In Concrete Slabs; Testing Insulation; Testing Drywall - Delmhorst navigator pro Owner's Manual

MEASURING RH IN CONCRETE SLABS IN ACCORDANCE WITH ASTM F-
2170:
Navigator Pro can be used to measure the RH in a concrete slab in accordance with the ASTM F-
2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs.
Basic Test Procedure:
 Drill 5/8-inch hole in concrete to the appropriate depth and remove debris from the holes.
Insert a CS-2 concrete sleeve into the hole and plug the sleeve with the cap that is provided
with each sleeve.
 Wait approximately 72 hours.
 Remove protective cap from the concrete sleeve and insert the RH/T-S3 humidity sensor into
the hole. Wait approximately 1hr to allow the sensor to acclimate to the RH in the hole.
 Connect one end of the RH/T-C1 cable to the top of meter and the other end to the exposed
end of the sensor. Take a RH reading using the RH/TEMP mode of Navigator Pro as
described on pages 10 and 17. This reading is the RH of the concrete slab.

TESTING INSULATION:

 Set the meter scale for PLASTER as described in the Create/Modify a Job section on page
11.
 To take a reading, attach a 21-E electrode with 4" insulated contact pins to the meter. Push
the contact pins through the drywall into the insulation behind it.
 Press the SELECT button and read the moisture content on the meter scale. The meter
displays the "relative" moisture level for two seconds.

TESTING DRYWALL

 Set the meter scale for Sheetrock® as described in the Create/Modify a Job section on page
11.
 To take a reading, push the contact pins into the Sheetrock® to their full penetration, if
possible.
 Press the SELECT button and read the moisture content on the meter scale. The meter
displays the %MC for two seconds.
