A double-ended diagnostic instrument combining an explorer tip and probe tip in one convenient tool. The Expro WHO/23 features color-coded, millimeter-marked tips made from spring-tempered stainless steel, precisely machine-ground and hand-finished to exacting tolerances. The color coding is applied under extreme temperatures to ensure the color penetrates the surface, and probe tips undergo additional tight tolerance grinding for optimal readability and measurement accuracy.
