The Delmhorst PX-30 is a paper moisture meter for paper mills, packaging and corrugating plants, printers, recyclers and conservators. It is calibrated for kraft paper from 4.3% to 18% moisture content and for baled scrap paper from 5% to 40%, with a 0 to 100 reference scale for materials that have no calibration. It replaces the Delmhorst P-2000.
It is a different instrument from a building meter. Paper moisture sits in a much narrower band, and getting it wrong shows up as curl, cracking, poor ink adhesion and jammed presses rather than structural damage. The paper calibration is what makes the readings useful.

Frequently asked questions
Can I use a building moisture meter on paper?
Not meaningfully. A wood scale will show a number on paper, but it is not calibrated for it, so the figure has no defensible relationship to actual moisture content. Where paper moisture matters commercially, use a meter calibrated for paper.
What is the reference scale for?
Materials with no published calibration — board, composites, unusual stock. It gives a relative number you can track over time or compare between samples, but it is not a moisture percentage.
Why does the alarm matter in a paper environment?
Because the acceptable band is narrow. With an alert set at the threshold, an operator checking a pallet does not have to interpret the number — the meter flags stock that is out of specification.
Support and warranty
The Moisture Meter Company (Aberford Holdings Pty Ltd) is the exclusive Australian distributor for Delmhorst non-agricultural moisture meters. Service, calibration questions and warranty claims are handled here rather than sent overseas.
Two year warranty on manufacturing defects. This does not exclude, restrict or modify your rights under the Australian Consumer Law. Our goods come with guarantees that cannot be excluded under the ACL. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.
What we see in the field
Paper testing gets messy when someone treats a bale, a thick core and a loose sheet as though they're the same material. Choose the right calibration and sample more than the exposed outside; that's where storage conditions can fool you. If the paper is valuable or historic, discuss the probe marks before testing.
