Ligno-DuoTec BW Moisture Meter

The Ligno-DuoTec BW is a non-invasive moisture meter with dual-depth measuring capabilities. Lignomat’s unique dual-depth moisture meters allow the user to have more versatility. Two moisture meters in one. Great for thinner and thicker boards, engineered floor planks, and waterborne finishes. In addition the RH BluePeg Probe can be added and used as a Thermo-Hygrometer or for RH in-situ probe testing of concrete following the latest ASTM F2170 standard.

For Contractors, Restoration Specialists, Floor Covering Installers and Inspectors.

Multi-function Moisture Meter:

Wood in Scan Mode: Ligno-DuoTec BW gives wood moisture readings in percent. Wood corrections are built-in for a measuring depth of 1/4″ and for 3/4″  for 70 specific gravity settings. Included are 9 different settings for bamboo.

Building Materials in Scan Mode: The Ligno-DuoTec BW gives moisture content in percent for drywall. However for concrete and light-weight building materials comparative readings can be taken to evaluate moisture conditions and find wet spots. Again 1/4″ and 3/4″ measuring depth are available. Conforms to ASTM 2659.

Air in RH Mode: Add RH BluePeg Probe for ambient relative humidity and temperature, GPP and DPT.  Moisture meter also used as a Thermo-Hygrometer.

Concrete in RH Mode: Add RH BluePeg Probes and RH accessories for in-situ moisture testing of concrete. Conforms to ASTM F2170. BW-KS package

The Ligno-DuoTec BW was designed for reliability and accuracy as well as sturdiness and ease of operation. The instruments have proven to perform well in rough mill environments with day-to-day usage.

Fast scanning of all flat surfaces of non-wood materials. Detection of different moisture levels in drywall, concrete, etc. RH BluePeg can be used as a measuring device for ambient relative humidity and temperature or placed in a measuring sleeve, which can be inserted into a predrilled hole in the testing area. Operation is that easy! Without studying pages and pages of operation manuals: Depress SET Button to check settings. Use up or down buttons to select correct setting. Depress % Button for moisture readings. Instrument turns itself off automatically.

At any time you can change from pin mode to scan mode by depressing up or down button. For more information on the Ligno-DuoTec BW please contact Customer Service for detailed quotes.
