The Delmhorst QuickNav is a 3-in-1 moisture meter for building inspectors, flooring installers and water damage technicians: pin mode, pinless scan mode, and a thermo-hygrometer for relative humidity and temperature. It calculates dew point, grains per pound and vapour pressure on the meter.
It has the Navigator Pro’s measuring capability in a simpler instrument. The difference is storage. As Delmhorst put it, if you want the versatility of a 3-in-1 and do not need to store and download readings, the QuickNav is the answer.

Relative humidity and ASTM F-2170
The RH sensor in the TotalCheck, QuickNav and Navigator Pro conforms to ASTM F-2170, the in-situ relative humidity test for concrete slabs. Flooring manufacturers write their moisture requirements against that standard, and a surface reading will not satisfy it.
A pin or scan reading tells you about moisture at or near the surface. In-situ RH tells you what the slab will do once a floor covering traps the moisture in it. On a flooring job, that second question decides whether you lay today or wait.
Choosing between the Delmhorst multi-mode meters
Four meters cover this ground. They differ on three things: how many measurement modes they have, whether they store and export readings, and whether they measure relative humidity.

Yes, with job and room structure |
Inspections and drying jobs needing readings organised by room and exported. |
The honest short version. If you do not need to store and download readings, the QuickNav does the same measuring as the Navigator Pro for considerably less — Delmhorst say so themselves. If your work is insurance-backed, or you hand over inspection or drying records, storage stops being a luxury and the TotalCheck or Navigator Pro earns the difference.
All four take the same external electrodes, so a 21-E or 26-ES bought with one meter carries across to the next.
Frequently asked questions
What does 3-in-1 actually mean?
Pin mode for a moisture content figure at a known depth, scan mode for finding moisture without marking the surface, and a thermo-hygrometer for air temperature and relative humidity. Three instruments in one body, so you are not carrying three.
Do I need storage?
Only if you have to prove what you found. For building reports, insurance and warranty work, a dated set of readings organised by room is what supports your findings. On maintenance work where you act on the reading and move on, storage is something you are paying for and not using.
Can I add electrodes later?
Yes. Every current Delmhorst meter accepts every Delmhorst electrode. The 21-E reads inside wall cavities and the 26-ES drives into timber flooring with insulated pins.
Is scan mode a moisture content reading?
No. Scan mode gives a 0 to 300 relative reference, not a percentage. Use it to find where the moisture is, then pin the area for a figure you can defend.
Who supports the meter in Australia?
We do. The Moisture Meter Company (Aberford Holdings Pty Ltd) is the exclusive Australian distributor for Delmhorst non-agricultural moisture meters, and handles service, calibration questions and warranty claims here rather than sending them overseas.
Support and warranty
One year warranty on manufacturing defects (owner's manual). 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
A pinless scan is great for finding the area worth investigating, not for declaring every high spot a leak. Run the meter over a known dry section of the same wall or floor first. If the construction changes halfway across, your comparison may have changed too.
