Fitted with the same 5/16" penetration pins that are mounted on our pin type meters. This electrode is great for a variety of different applications:

  • Home inspector: Use on wood joists and drywall.
  • Paper producer: Use on curved surfaces such as cardboard and paper tubes.
  • Woodworker: Use on timber, poles, and veneer.

2-E is also available as the 2- ET with a tapped handle for hard to reach areas. Can also be fitted with A-103 uninsulated pins with 1 3/32” length and 11/16” penetration.

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.

(Price: $150.00)

21-E.jpg

21-E

The 608 pins that come with the 21-E are insulated, except at the tips, and can reach a maximum penetration of 3-1/4".

Great for use on roofs, insulation, or EIFS.
