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.
