To ensure universal compatibility, the chemical-resistant PTFE female sheath can be easily trimmed with a clean blade if your electrode's connecting lead is shorter than 20 mm. Trimming guarantees a flush, stable fit and a solid, noise-free electrical connection. Contact us if you require the female sheath needs to be pre-trimmed by us before shipping.\u003cbr\u003e\u003cbr\u003eTo maintain optimal performance and signal integrity, ensure the internal electrical connections remain completely dry and free from electrolyte splash. Preventing liquid contact inside the female receptor avoids localized corrosion, which can otherwise introduce unwanted resistance and electrical noise into your measurements.
