Precise, durable test probes: 100 brass test probes, 2.0 mm, designed for repeated use. Four test detections with accuracy up to 0.02 mm provide reliable size adjustment and consistent measurement results. Stable spring-contact design: The model spring test contacts are engineered for dependable contact and stable readings during probing. Spring action helps maintain consistent pressure and reduces false readings from poor contact. Broad compatibility and versatile use: Suitable for testing contaminated PCB cards, pierced or layered contaminated circuits, pins, and solder bandages. These probes work across a variety of board and component testing scenarios. Built for long-term use: Brass construction offers corrosion resistance and mechanical durability for repeated probing in lab, repair, and production environments. Technical highlights Quantity: 100 pieces per package Probe diameter: 2.0 mm Accuracy: up to 0.02 mm Material: brass Design: spring test contacts for stable electrical contact Practical applications (examples) Repair bench: Inspect and troubleshoot contaminated or oxidized PCB pads and through-holes without damaging surrounding traces. Production testing: Use as replacement probes or extras for spring-loaded test fixtures that require consistent contact force and repeatable readings. Hobbyist/DIY electronics: Probe pins, headers, and solder bandages when diagnosing solder bridges, cold joints, or intermittent connections. Why choose these probes High repeatability and fine accuracy reduce time spent re-testing. Brass construction and spring-contact design minimize wear and maintain performance over many cycles. A 100-piece pack covers professional test requirements and DIY projects alike.
