Delrin is used here because it is dimensionally stable, machines accurately and holds its insulating properties under the repeated shock loading a slide hammer applies.\u003c\/p\u003e\n\u003ch2\u003eWhy it is a service part\u003c\/h2\u003e\u003cp\u003eOn a resistance meter, the insulation between the two pin circuits is what makes the reading meaningful. If it degrades or cracks, current leaks between the circuits and the meter reads high — a wet reading on dry timber. It is a quiet failure, because the meter still switches on and still displays a number.\u003c\/p\u003e\u003cp\u003eIf a hammer electrode has started reading consistently high, or reads a moisture content with the pins in clear air, suspect the insulation before you suspect the meter.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\u003cp\u003eSupplied for the Delmhorst 26-E hammer electrode assembly. Delmhorst does not publish a specification for this part in its online catalogue, so we have not stated dimensions we cannot verify.

A resistance meter measures between the pins; if the head is conducting, the reading includes that path rather than only the timber.\u003c\/p\u003e\n\u003ch3\u003eIs it a workshop job?\u003c\/h3\u003e\n\u003cp\u003eYes, and a straightforward one. If you are not confident dismantling the electrode head, send it to us rather than guess — a mis-seated insulator produces readings that look plausible and are not.\u003c\/p\u003e\n\u003ch3\u003eWhy Delrin rather than a cheaper plastic?\u003c\/h3\u003e\n\u003cp\u003eIt stays dimensionally stable and holds its insulating properties under the repeated shock a slide hammer applies. A softer plastic deforms, and once the geometry moves the readings move with it.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eNot sure which part suits your meter?
