Moisture Meters - Trouble with Delmhorst RDM-3
« on: June 15, 2017, 10:33:14 AM »
Has anyone had trouble with the Delmhorst RDM-3?

We have 2 of them. Both are less than a year old and we have already had to get them both fixed. They aren't working properly again and our guys are reverting back to using the old Delmhorst meters that we have from 15+ years ago.

We use them to check the material in and out of the kiln. We find that they end up giving the same reading over and over (example: the screen will be at MC 12.4% when pins are not touching anything and remain at 12.4% through 5-10 different samples). We find that the problem is intermittent.

Has anyone had a similar experience with these meters? Can it be fixed? Is there a better option out there?

Sorry to hear of your problems with the usually reliable RDM-3. The issue sounds like electrical leakage in the meter or electrode which often can be remedied by cleaning the input connector and contact pins assembly as well as the insulation assembly of the electrode with denatured alcohol or a mild bio-degradable cleaner. If the issue persists, please use the Return Form on our website and return the equipment to us for evaluation and repair.

Thank you.
