PTM 2.0 Professional Pin-Type Moisture Meter

The PTM 2.0 Professional Pin-Type Moisture Meter is a hand-held, digital, pin-type resistance moisture meter designed to take precise measurements of moisture content in wood, to test the moisture conditions of drywall and give comparative WME (Wood Moisture Equivalent) readings in wood by-products and other building products.

The PTM 2.0 has built-in calibration for over 500 wood species and settings for temperature correction.

It works on the principle of DC resistance. When the electrode pins are pressed or driven into the wood, the electrical resistance between the electrodes is measured. If the wood is dry, the resistance is high.
If moisture is present in the wood the electrical resistance between the pins changes. The higher the moisture content the greater the reduction in resistance.
The level of resistance is accurately measured by the instrument, which translates it into a moisture value.
This is a percentage of dry weight moisture content for wood, a relative scale for drywall, and a WME wood moisture equivalent value for many other building materials.

The PTM 2.0 Professional Pin-Type Moisture Meter incorporates a number of standard calibration settings:

• Fir, Douglas - USA 
• Fir, Douglas - AUS 
• Oak - Europe 
• Furu (Pine) - SWE  
• Gran (Spruce) - SWE  
• European Redwood - UK  
• Scots Pine - PTM 1.0

Different species of wood can vary in density and conductivity, which can have an effect on the electrical resistance of the wood. The Professional PTM 2.0 has been programmed with 500+ species in order to give precise moisture content readings for each selected wood species.

The PTM 2.0 will give readings in wood of 6% to 46%MC moisture content. It should be noted that readings above 27% (nominal value of the fibre saturation point) are indicative only.

It can save up to 100 readings in its memory from any of the 3 Modes – Wood, WME (Ref) or Drywall.
