hIf you are testing high density bales, we recommend using the H-3 handle with the 830-2 10” prod, 830-3 18” prod, or the 830-4 36” prod. Using the handle/prod combina- tion eliminates excess stress on the instrument case that may occur when trying to insert the prod into a high den- sity or large bale.
Test B hAttach the #831 short pin prod to the H-3 handle and connect the handle to the external connector on top of the meter. hApply the prod to the hay in the windrow and press down on the electrode handle until the head of the screw touches the palm of your hand.
6%-30% or 13-40%, depending on model. Readings over 30% should be used only as a qualitative indication of high moisture content. Delmhorst moisture meters use the relation- ship existing between electrical conductivity and moisture con- tent in hay. As moisture content increases, so does the con- ductivity.
The validity of the meter readings is closely related to the care spent in sampling the hay to be tested. Whether hay in the windrow or baled hay is tested, the number of tests made should be increased whenever the initial readings show considerable variations.
Sample Size When testing baled hay, it is essential to take readings at several different points in the bale. Hay moisture may vary a great deal in the same bale. For example, at one point bale moisture may be 20% and at another over 35%. More tests must be made whenever the variations among readings are greater.
