Over 50 Years of Quality, Accuracy, and Service
That's why so many companies rely on Delmhorst resistance technology and
accuracy, proven by university and independent studies. Resistance technology
is the standard around the world. It is the only real way to identify surface
and core moisture content, minimizing defects and improving quality control.
Whether you're a home inspector, claims adjuster, or homeowner, a Delmhorst
moisture meter is the only tool that will tell you the job is done right!
By checking moisture conditions at any stage of a home inspection, water
damage claim, or EIFS job, you will be able to sign off with confidence that
the structure is dry. Our wide assortment of models gives you the opportunity
to select the right meter for your needs.
All Delmhorst meters include these outstanding features:
- Rugged carrying case, batteries and extra contact pins
- Temperature stable circuits - no need to make adjustments before taking a reading
- Built-in battery and calibration checks -
gives you confidence in performance and primary calibration
Frequently Asked Questions
- WHY SHOULD I USE A MOISTURE METER?
- Home inspectors, pest control operators and EIFS inspectors know
that moisture intrusion is the single most important factor affecting
the integrity of building structures.
- We offer moisture meter packages specifically manufactured to meet the
needs of inspectors.
- Proper use of a moisture meter allows the inspector to easily
identify the source moisture and to locate areas in the building
that have been affected by moisture.
- HOW DOES A MOISTURE METER WORK?
- There are two types of moisture meters typically used by the home inspector.
- Pin-Type meters, which utilize the principle of electrical resistance,
use wood or other hydroscopic materials as an element in a circuit by
driving two pins or electrodes into it.
- Pin-less meters like the Accuscan uses radio frequency signals to
penetrate the material being tested. There is no pin intrusion into
the surface of the material you are checking.
- CAN I USE A MOISTURE METER TO CHECK FOR PEST INFESTATION?
-
YES - a few meter readings in key locations of the structure will
quickly indicate if the areas are safe or in danger of infestation.
We recommend using pin-type meters for pest control application as
the best way to identify the exact point of infestation behind walls
and ceilings. The key to finding hidden moisture is to use an electrode
with insulated contact pins. These pins read only at their un-insulated
pin tips, allowing the contractor to drive the pins into materials at
different depths, noting readings at each level of penetration.
A pin-less meter is a good way to identify infested areas, as long
as you do not have to penetrate into a hidden material.
- AT WHAT LEVEL OF MOISTURE DOES INFESTATION OR DECAY OCCUR?
- Readings over 20% MC clearly indicate that wood is subject to
infestation and possible decay. Readings in the 17% - 20% are
borderline and normally require further testing.
- WHICH TYPE OF MOISTURE METER WORKS BEST FOR EIFS?
- A pin-type meter is the best way to identify the exact location of
moisture in the substrate and framing
- A pin-type uses tow pins that penetrate into the building at the
user's desired depth.
- When insulated pins are used, only the uncoated tips are exposed
to the wood fiber, providing an accurate reading of moisture
content at various levels of penetration.
- Pin-type meters are the only instruments that allow the inspector
to identify exact location of moisture at a given point.
- Many EIFS inspectors use both types of meters. They can quickly
identify problem areas using a pin-less meter, and also use a
pin-type meter to identify exact location of moisture in the
wood substrate.
- WHERE DOES MOST MOISTURE INTRUSTION OCCUR IN EIFS CLAD HOUSES?
-
Most moisture intrusion occurs around windows, doors and any flashing.
In many cases, the moisture intrusion is directly related to poor
installation practices.
- HOW CAN I FIND MOISTURE IN THE SUBSTRATE OR FRAME OF THE HOUSE?
-
The most effective way to check for moisture in the substrate or frame
is to use our 21-E electrode with 6" penetration pins. This method
allows you to locate moisture behind the EIFS without it having to be torn away.
- HOW DO I KEEP A DELMHORST METER IN GOOD WORKING CONDITION?
-
Delmhorst moisture meters are well known for their ruggedness and ability
to withstand years of rough handling. Like any testing instrument, a
little care goes a long way toward trouble-free service.
- Store the meter in clean, dry place
- Change batteries and pins as needed
- Keep the meter and electrodes clean
- By using any biodegradable cleanser sparingly on external parts only.
