MCS-1.jpg

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. The MCS-1 is also available with a letter of certification traceable to NIST.

J-4 Electrodes:

Delmhorst offers a wide assortment of electrodes known throughout the industry for their durability. All Delmhorst electrodes fit any Delmhorst moisture meter. Below are electrodes that are typically used for this model:

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.

2-E.jpg

2-E

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.
