26-ES Wood hammer
Hammer electrode. The 496 contact pins that come with the 26-ES penetrate 29mm (1⅛”) 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.
Also available as the 26-ED, which includes gauge to measure pin penetration depth.

This hammer electrode will easily check high density hardwood that short pins are unable to penetrate. It will also easily penetrate through flooring to plywood sub-floor or concrete.

2-E Building materials
Fitted with the same 8mm (5∕16") penetration pins that are mounted on our pin type meters.

Electrode great for hard to read areas.
Use on wood joists and drywall.

Moisture content standards are great for verifying that your Delmhorst moisture meter is in calibration. The MCS-1 can be used on any meter with a wood scale. With two electrical resistance values (12% and 22%) to test your meter against, you can be sure that your readings will stand up to the strictest standards of accuracy.
Uninsulated pin and retainer with 8mm (5/16") penetration.
Standard on all meters with built-in pins and the 2-E and 4-E electrodes.

Used on wood up to 38mm (1 ½”), concrete and gypsum.
496 contact pins are insulated except at the tips, and measure 5cm (2") overall with 29mm (1 1/8") penetration.
Standard on the 26-ES.

Used to check wood up to 13cm.
An alternate to the 496 pin for the 26-ES, the 1849 is a 38mm (1½”) insulated pin with 13mm (1/2") penetration.

The 1849 is suitable for wood up to 5cm (2") thick.
Another alternative to the 496, the A-111 is an uninsulated contact pin measures 36mm (1 7/16”) and has 1,3cm (1/2") penetration.
The A-111 is compatible with both the 26-ES and the 22-E, and its tapered point makes it easier to penetrate into hard surfaces.

Can be used on wood up to 5cm (2") thick.
Retainer used to hold contact pins in place.

Used with # 496, # 1849, and # A-111 pins.
