Package M-11


To monitor lumber drying – for all sizes and types of dry kiln – from solar to conventional steam kilns. Whenever moisture in wood and other solid materials should be measured and monitored, but the location cannot be reached with a handheld electrode.


The mini-Ligno MD/C is our best priced pocket-size meter. The measuring range is 6-25%. It covers the critical range below fiber saturation point to monitor lumber drying.

  • Measuring moisture in the center of a kiln charge gives representative results of the drying progress and allows determining the time when the lumber is dry and the kiln ready to unload
  • An inexpensive way to monitor structural wood in critical areas of the building envelope, crawl spaces, attics, roofs, wall studs…

Product Description

Package M-11 for In-Kiln Moisture Measurements

Lumber drying – for all sizes and types of dry kilns – from solar to conventional steam kilns. Use the M-11 package for easy access in-kiln moisture measurements. 

The PK probe and cable system is designed to monitor places, that are otherwise unreachable. For example, the middle of a lumber charge in a hot dry kiln, studs in a crawl space or structural lumber in a roof…

The mini-Ligno MD/C offers Lignomat quality at its best price. With a measuring range of 6%-25% it is wide enough to cover all applications from woodworking to home construction and home restoration, lumber drying, even measuring firewood. 2 Correction settings are built-in for measuring hardwoods, softwoods and panel products.

In fact, PK probes and cables have been used to measure lumber inside dry kilns for over 50 years and are still being used today with Lignomat’s dry kiln control systems for industrial kilns. If multiple probes and cables are used, kiln performance can be checked by distributing the cables in top, bottom, sides and middle sections of the kiln. Also, cables are standard 6ft long, but can be custom-cut upon request up to 25 ft long. 

All probes have a hole in the head for pushing a 4 mm banana plug through. This is a fail-proof connection. The probes have teflon-coated shanks, which insure that moisture is measured where the tip of the PK probe is and measurements are not affected by surface moisture. Probes are inserted into pre-drilled holes and are set and removed correctly with the Pulling Tool.

All PK probes are made out of stainless steel to withstand the harsh conditions in a kiln. They can be re-used for many drying cycles. Using the pulling tool will help to set and remove probes without any damage.

In addition, PK probes can be used in many materials other than wood, such as concrete, brick, tile, roofing. They monitor changes in moisture content at the depth where the tips of the probes are placed. PKB probes are standard with M-11 Package.

PKA: measuring depth 1/2″ (1.2cm) 4/4 lumber
PKB: measuring depth 3/4″ (1.9cm) 6/4 lumber
PKC: measuring depth 1″ (2.5cm) 8/4 lumber
PKD: measuring depth 1 1/2″ (3.8cm) 12/4 lumber
PKE: measuring depth 2 3/4″ (7cm)

Measurements from PK probes can be obtained with handheld moisture meters and data loggers for in-kiln moisture measurements:

Cables: The PK-mini cables have 4mm plugs on one end to fit PK probes and 2mm plugs on the other end to fit the mini-Ligno MD/C. The PK-mini cable is made with a pair of teflon-insulated, twisted, shielded wires for reliable transfer of measurements and to be heat resistant.

The cables included in the M-11 package are 6ft long. Upon request we can supply longer cables, please call customer service at 800-227-2105 for a quote. 


  • Add depth-slide-hammer electrode E12 and mini-BNC cable to spot-check lumber anywhere at any time. Pins are available for core measurements up to 2″ deep.  
  • Add electrode E14-m for measuring wood, even extremely hard wood up to 1/2″ deep. Hammered into the wood with a hammer.
