Introduction 

 
 
Congratulations! 
 

You have purchased one of the most accurate moisture measurement instruments for wood in the world.  
Using patented electromagnetic wave technology, hand-held moisture meters from Wagner Meters have 
been proven by universities and institutes worldwide to provide superior measurement results. 

 

With its electro-magnetic field, your Wagner moisture meter covers a relatively large cross-sectional area

1

 

each time you take a reading, giving you a far better representation than other technologies of the true 
moisture content of your wood.  Pin-type meters only measure a very small area, and only at a particular 
depth, giving you very limited insight into the true moisture content of the wood. Very short, non-
insulated pins are especially prone to just reading the surface of your wood.  Wagner moisture meters read 
IN the wood, not just on the wood.

approximates the full-thickness cross-section method used when performing the ASTM D 4442-92 oven-
dry lab method. This ASTM standard (and its international counterparts) is the standard to which all 
moisture meters for wood are compared for accuracy.   

 

 
Other important features of Wagner  hand-held moisture meters include: 

 

 

The L601-3 DF Meter uses advanced electromagnetic wave technology to accurately measure wood 
moisture content.

Virtually unaffected by wood temperature or surface moisture.

The "Wood-Friendly"™ L601-3 DF moisture meter does not damage your wood or its surface while 
taking accurate moisture readings. 

 
 
Since 1966, Wagner Meters has been providing quality moisture measurement equipment. Wagner Meters 
is the leading supplier of moisture measurement equipment for the primary forest products industry. 
Wagner Meters’ technology has been proven to provide some of the most accurate results in the industry 
when compared to this worldwide standard. Closely scrutinized and approved by numerous university 
studies  and used for years by professional wood-grading associations, moisture meters from Wagner 
Meters continue to provide reliable and consistent moisture measurements, with unsurpassed convenience 
and ease-of-use.
