How Do I Keep a Delmhorst Moisture Meters 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 electrode clean by using any biodegradable cleanser sparingly on external parts only.
If you have any doubt about the working condition of your moisture meters, send it to Delmhorst. We can repair and re-calibrate your instrument to its original standards and return it to you quickly.
If you have any further questions on using your moisture meters, please call us at 1.888.270.2690 or fill out our Request Form under Contact Us.
How Do Delmhorst Moisture Meters Handle Readings on Rough-Surfaced Lumber and Cupped Boards?
With a pin-type meter, these conditions are not a problem. Just drive the pins as you would normally, insuring firm, positive contact and detect unknown gradients. Pin-less meters, however, need full exposure to a flat surface so their readings on some uneven surfaces may be unreliable.
How Many Measurements Does Delmhorst Recommend for an Accurate Sampling?
Accuracy of the readings depends on how representative the samples are of the entire load. In an ideal situation, when all the boards in a load have the same moisture content, and the distribution in each board is uniform, only a few readings are needed.
But since this ideal condition doesn't often happen, start by checking a large percentage of pieces. If the readings are within close range, it's apparent that the load is fairly uniform. For critical use, check 5 or 10 percent of the load, and be sure to look at boards from all parts of the load. Check slower drying quarter sawn boards as well as flat sawn lumber. If you can only drive pins into the edge, be sure to use the longest pins available to reach the fibers as deep as the board is thick.
The Delmhorst RDM series moisture meters with data collection and statistical analysis capabilities are ideal for simplifying the entire sampling procedure and providing backup documentation.
Are Delmhorst Moisture Meters Accurate on Frozen Lumber?
As long as the wood is not frozen solid and remains conductive, a pin-type meter will give reliable readings. However, most instrumentation, unless specifically designed for extreme weather conditions, will not work well in constant sub-freezing temperatures.
