The Delmhorst QuickNav is a 3-in-1 moisture meter: 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 is the Navigator Pro’s measuring capability in a simpler instrument. The difference is storage. Delmhorst put it plainly: if you want the versatility of a 3-in-1 and do not need to store and download readings, the QuickNav is the answer. What is in this package QuickNav meter with RH sensor Carrying case 2-E electrode Specifications Pin mode 6% to 60% wood, 0.1% to 6% drywall Pin penetration 7.9 mm (5/16 inch) integral pins Correction Wood and drywall correction scales Scan mode 0 to 300 numerical reference scale Relative humidity 0 to 100% RH Calculates Dew point, grains per pound, vapour pressure Storage None — readings are taken and used, not stored Warranty 1 year 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. That matters because 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 the second question is the one that decides whether you lay today or wait. Choosing between the Delmhorst multi-mode meters Four meters cover this ground and they separate on three things: how many measurement modes, whether the meter stores and exports readings, and whether it measures relative humidity. Meter Modes Stores readings Suits TechCheck Plus Pin and scan No Two-mode work without RH. Freezes a reading taken out of sight. QuickNav Pin, scan, RH No Full 3-in-1 capability where you record readings yourself. TotalCheck Pin, scan, RH Up to 1,400 with date and time stamp Documented drying records, job groupings, PC download. Navigator Pro Pin, scan, RH Yes, with job and room structure Restoration work 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 are handing over 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 quantitative moisture content at a known depth, scan mode for finding moisture without marking a 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. On insurance and warranty work, a dated set of readings organised by room is what supports the claim. On maintenance work where you act on the reading and move on, storage is weight you are paying for. Can I add electrodes later? Yes. All Delmhorst electrodes fit all current Delmhorst meters. 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 to get a number you can defend. Who supports the meter in Australia?
