#10 Wagner Meters Vs. Pin-Type Meters 

Q

: How can I take accurate moisture readings without sticking pins into my wood? Why doesn’t my new 

hand-held meter from Wagner Meters read the same moisture content as my old pin meter? 
 

A

: Pin-type meters work on a primitive resistance principle that basically measures the flow of electricity 

through a substance. This method is subject to many environmental variables that can dramatically affect 
moisture readings such as chemicals in the water trapped within the wood and the temperature of the 
wood. Pin-type meter readings must always be corrected for any difference in temperature above or below 
70 degrees F. Hand-held moisture meters from Wagner Meters use advanced electro-magnetic wave 
technology and are sensitive to changes in density and the actual moisture content of the wood. 
 

 

#11 4x or Larger Lumber 

Q

: Can I get accurate results on 4x or larger lumber? 

 

A

: No hand-held moisture meter can accurately read to the center of 4x material unless you are willing 

and able to drive pins 1" into the lumber all the way up and down its length and breadth. However using a 
hand-held moisture meter from Wagner Meters, you can quickly and easily scan 4x lumber on both sides 
(4 x 4’s on all four sides). Then only the center 1 5/8" would be unmeasured. 
 
Note: Most wood grading agencies are generally not concerned about the moisture content in the center of 
thicker beams and posts. They consider 1" deep scanning more than adequate. 

 

 

#12 Relative Humidity 

Q

: What are the effects of relative humidity on readings with hand-held moisture meters from Wagner 

Meters? 

 

A

: As long as there is not condensation on the bottom surface of the instrument there is no effect from 

changes in relative humidity. 
 
 

#13 Calibration 

Q

: Does my hand-held moisture meter from Wagner Meters need to be calibrated? If so, how often must 

it be done? 
 

A

: Occasionally hand-held moisture meters from Wagner Meters require adjustment. However, the 

process of checking zero points and calibration is very simple. 
 

Note

: Meters from Wagner Meters are originally calibrated at the factory. Type and amount of use will 

determine how long this original calibration will last. A calibration verification block is available for the 
customers who must check their calibration often. Anytime that the meter is not reading correctly on that 
calibration block, it should be sent to the factory for calibration.
