L722 STACK PROBE ATTACHMENT
The Model L722 Stack Probe attachment, coupled with the L612 or L622 (latest
version) Digital Recording Moisture Meter makes it easy to reach deep into stickered
units of lumber and take accurate moisture readings without the danger of broken
pins. Wagner’s “Wood-Friendly” electromagnetic wave technology makes it possible
to take multiple readings throughout an entire stack in just minutes.
NOTE: The L722 will work with either the L612 or the L622, for the remainder of this
manual, the L622 will only be referenced.
Once the probe is inserted between the boards, the springs press the end-mounted
sensor flat against the wood and ensure deep penetration of the electro-magnetic
field. You then slide the probe slowly out of the stack, reading the moisture in each
board as the sensor passes over it. Virtually unaffected by surface moisture, the L722
gives consistent and reliable readings in or out of kilns.

L722 CALIBRATION
Calibration is factory set. Calibration may be checked by using the Calibration
Verification Block (included with the L622), and following the instructions in the L622
Manual. The probe calibration is verified in the same manner as the L622 (Refer to
the L622 Owner’s Manual).
