The Delmhorst JX-30 is a timber moisture meter for flooring installers, joiners, cabinet makers, timber suppliers and building inspectors. Where the BDX-30 covers wood, drywall and general building materials, the JX-30 concentrates on wood and carries far more species data — 197 species corrections available through the EDGE app, with up to 100 held in the meter at once. It replaces the Delmhorst RDM-3 and J-2000.
Species data matters because timbers give different resistance at the same moisture content. On flooring, joinery and timber supply work, the right species correction separates a reading you can put in a report from one you cannot.
It also corrects for whether you are using insulated or non-insulated pins, which most meters do not.

Frequently asked questions
Why does species selection matter so much on timber?
Different species give different electrical resistance at the same moisture content. Reading jarrah on a Douglas Fir setting can be several percent out — enough to lay a floor that should have waited. The JX-30 gives you 197 species corrections through the app, with up to 100 held in the meter. For Australian timbers, see also our Australian Timber Species Correction Tables and the general Correction Tables.
Insulated or non-insulated pins?
Non-insulated pins read the wettest point anywhere along their length. Insulated pins read only at the tip, which is what you need to measure a moisture gradient through a board. The JX-30 corrects for whichever type you are using.
How does this differ from the BDX-30?
The BDX-30 covers wood, drywall and general building materials, with 37 species corrections in its app. The JX-30 is wood-focused, with 197. Building inspection and water damage work suit the BDX; timber flooring, joinery and timber supply suit the JX.
Can I add electrodes later?
Yes. Every current Delmhorst meter accepts every Delmhorst electrode.
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
Before someone rejects a load of timber on a single high reading, we'd want to know the species and where the pins went in. Check a few boards at different points and apply the meter's species correction. The number only means something if the test method stays the same.
