L622 Digital Recording Moisture Meter
Wagner introduces the L622 Digital Recording Hand-Held
Moisture Meter. This new model replaces the proven
L612 model instrument, providing improved moisture
measurement accuracy in the 15%+ moisture content
range. As with the L612 model, the L622 utilizes
Wagner’s Intellisense™ technology to truly read the
moisture IN the wood, not ON the wood.
• Stores and displays up to 33 user-selected species
adjustments by name.
• Stores up to 5000 separate moisture readings.
• Stores readings in up to 200 groups.
• Built-in real time clock/calendar.
• Send reports directly to a printer or data to a
computer for advanced analysis using supplied Stat-
Pak software.
Using non-volatile memory, stored readings are retained
even when the batteries are removed. A backlit LCD
display features a 2-line, 32-character display. Function
buttons and scroll arrows operate a menu system that
guides the user step by step through the selecting,
storing and reporting process. The meter has auto-shut-
off to extend battery life.
Like all Wagner Hand-Held Moisture Meters, moisture
readings are virtually unaffected by wood temperature in
the normal operating range outside of a kiln environment.
Refer to the stack probe manual for more information
about measuring wood in kilns. Contact Wagner
technical support for guidelines when wood is below
freezing.

*Battery life is significantly reduced when using the display backlight.
It is recommended to use rechargeable Nickel-Cadmium or Nickel-
Metal Hydride batteries when extended backlight usage is planned.
The Ni-Cd or Ni-MH batteries and charger may usually be purchased
at most electronics supply stores. Be sure to use a battery charger
that has a battery conditioner and an auto shut-off feature to avoid
over charging of the batteries.
