Product Specifications



How does it work?  AccuDry® is an in-Kiln moisture measurement system that provides precise visibility of the Wood Moisture Content, throughout the drying process.  AccuDry® measures how the wood affects electrical signals as they are passed through the stack inside the Kiln.  Two stainless steel electrode plates are inserted into the wood stacks, to which the AccuDry® meter is connected to with alligator clamped cables.  The AccuDry® system, mounted nearby on the kiln, injects low voltage electrical signals into the wood through one plate, and returns it to the meter through the second plate.  Using its patented technology, the AccuDry® meter measures the change of the signal, and applies scientifically proven algorithms to determine the dielectric conditions of the wood.  The results are then sent to an AccuDry® display screen so the kiln operator  can monitor the current moisture content of each individual wood stack (i.e. kiln zone).  AccuDry® can also be connected to programmable logic controllers (PLCs) to interact with kiln control systems. 


Installation Process:  An authorized contractor will install AccuDry® (approx. 2 days).  Kiln Operator is responsible for installing conduit with RS485 Plenum Cable between controller location & kiln.   AccuDry® meter(s) are mounted on kiln outer

wall and are cabled back to the control unit, which will be installed near kiln control system, or as desired.  Activation and

calibration is performed onsite by an AccuDry® engineer.


Warranty:  5 year limited warranty for the AccuDry® system: Stack Probe hardware 5 yrs; New Electronics 2 yrs; Rebuilt Electronics 1yr; Installation Labor 90 days.  See full warranty statement for complete details.
