Delmhorst H-4 is an electrode handle that attaches to the built-in connector on the top of any moisture meter. Can be used with the 830 series prods, 831 short pin disc shaped prod, and 832 long pin disc shaped prod. This is useful for large or high density bales of hay or scrap paper. Two handed operation is recommended over using a prod that connects directly to the top of the meter to minimize stress placed on the meter casing Features:
