26-ES.jpg

26-ES

The 496 contact pins that come with the 26-ES penetrate 1 1/8” and have insulated shanks so that only the tips are exposed. The pins make contact only at their uncoated tips and provide much more accurate readings of moisture content at various levels of penetration. This feature is useful for a variety of different applications:

  • Flooring installers: Penetrate through flooring to plywood sub-floor, or concrete.
  • Dry kiln operators: Identify moisture gradients which helps to identify the drying pattern.
  • Furniture manufacturers and craftsmen: Easily check high density hardwood that short pins are unable to penetrate.

Also available as the 26-ED, which includes gauge to measure pin penetration depth.
