Wood species and moisture content

Based on the oven dry method, the calibration of the Humitest moisture meters for different wood species depends on the technology of wood.

The moisture testers Humitest Mini, Humitest Survey, Humitest Timb et MMS are calibrated for wood from 7% on dry wood to fibre saturation* (30% on wet wood, that is to say 23% on dry wood).

Wood species corresponding to the standard calibration (A)

Afara ; Ash, European; Ash, Japanese; Balsa; Banga Wanga; Birch, Yellow; Bosquiea; Boxwood, Maracaibo; Cypress, E African ; Dahoma A; Fir, Grand ; Gum, American Red; Gum, Spotted; Gurjun; Kapur; Karri; Kuroka; Maple, Pacific; Maple, Rock; Maple, Sugar; Myrtle, Tasmanian; Oak, American Red; Oak, American White; Oak, European; Oak, Japanese; Padang; Panga Panga; Pine, Lodgepole; Pine, Scots; Pine, Yellow; Poplar, Black; Pterygota, African; Redwood, Baltic (European); Rosewood, Indian; Sen; Sterculia, Brown; Tallowwood; Walnut, American.

When measuring one of the wood species listed hereafter, the user of the Humitest Timb moisture meter selects the calibration corresponding to the measured wood species thanks to the calibration table for wood species. With the Humitest Mini, Survey et MMS moisture meters, the user amends himself the measured water content refering to the calibration corresponding to the wood specie he lmeasures.

With the Humitest for round timber moisture meter, the customer specifies when he orders its moisture tester if he wants the display of the water content on dry mass or on dry weight. The list of the calibrations that follows is regularly enriched. Please do not hesitate to contact Domosystem if the wood species to be measured does not appear in it.

Main Group	Sub groups	Valid measuring Range
Beech	Rubber	32%
Oak	Mahogany, Wenge	32%
Alder	Acacia, Alstonia, Birch, European chestnut, Horse chestnut, Cherry Tree, Walnut, Okan	40%
Ash	Keruing	35%
Spruce		40%
Pine	Balsa, Yew Tree, Stone Pine	35%
Larch	Maple, Douglas Fir, Hemlock, Cotton Wood, Elm	32%
Fir	Ceiba, Linden	37%
Willow	Pear, Hickory, Olive wood, Ramin, Teak	40%
