The Delmhorst RC-1E is an analogue wood moisture meter in a hardwood case. It reads 6% to 80% moisture content across a three-range analogue scale, with a temperature-stable circuit and built-in battery and calibration checks.
An analogue needle still has a place. It responds instantly and continuously, so sweeping across a board shows a gradient rather than a series of settled digits, and there is nothing to boot up or run flat mid-reading in the way a digital meter can.

| Circuit | Temperature stable |
| Checks | Built-in battery and calibration check |
| Shut-off | Automatic |
| Case | Hardwood |
Who it suits
Timber yards, sawmills and kiln operators working well above the range digital building meters cover — 80% is green timber territory, not building moisture.
Who it does not suit. Anyone needing recorded or exported readings, species correction from a menu, or drywall and concrete scales.
Compatible electrodes
The RC-1E takes standard Delmhorst wood electrodes. These are the useful ones for timber work.
| Electrode | Type and use |
| 26-ES | Slide hammer with insulated 496 pins, 29 mm penetration — the primary recommendation for timber |
| 26-ED | As the 26-ES with a penetration depth gauge |
| 2-E | Two-pin general purpose wood electrode |
| 2-ET | 2-E with a tapped handle for an extension pole |
| 4-E | Four-pin surface and general wood electrode |
| 15-E | Eight-pin electrode for thin stock and veneer |
| 22-E / 22-ET | Two-pin electrode for wood and building materials |
| 830 series | Long probe for sawdust and wood products — requires the H-4 handle |
| 42-E/B | T-handle electrode, shallow penetration |
| 19-E | Blade type wood electrode |
Linked electrodes are stocked here. The 2-ET, 4-E, 15-E, 42-E/B and 830 series are compatible but not currently held — ask us and we will bring one in.
Frequently asked questions
Why 80% when building meters stop at 60%?
Because green and freshly sawn timber sits above the range building work deals with. If you are drying stock rather than checking a finished structure, that upper range is the reason to choose this meter.
Is analogue less accurate?
Not inherently. It gives a continuous reading rather than a sampled one, which suits sweeping a board. What it does not give you is a number to store, correct or export.
Does it take Delmhorst electrodes?
Yes — see the compatibility table above. The 26-ES slide hammer is the primary recommendation for timber work.
Support and warranty
Carpet Cleaners Warehouse is the exclusive Australian distributor for Delmhorst outside the agricultural sector. Service, calibration questions and warranty claims are handled here rather than sent overseas, and we hold electrodes and pins in stock.
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.
