Electrodes
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.

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


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.



Benefits
  • 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.

19-E Wood
Blade type electrode.

Available blade lengths:
125mm (5”)
300mm (12”)
450mm (18”)

Benefits
Electrode designed for measuring in wood pellets, shavings, tree bark, etc.
15-E Wood
Pin type, with two rows of four pins each, maximum penetration 3mm (⅛"). Penetration can be adjusted according to stock thickness by means of gauge block

Benefits
Used for veneer
26-ES Flooring
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.

Benefits
This hammer electrode will easily penetrate through flooring to plywood sub-floor or concrete.

Accessoires
MCS-1
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.
2498/A-100
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
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.
1849
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.
608
The 608 insulated contact pins measure 10cm (4") overall, and penetrate 8,25cm (3 1/4").
Standard on 21-E and 18-ES electrodes.

Used on roofing, insulation, timber, poles, and EIFS.
