The 26-ES Contact Pin Electrode has 496 contact pins
They 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.
Good for 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.
