Digital Electrode with Matchin Pin - 3.5 mm Connector
Like the DIN connectors above the quick connect DIN connector is proprietary to specific meters. The quick connect DIN connector simply pushes onto the meter. A rubber O-ring is used to fix the connector to the meter and provides a waterproof connection. Waterproof connectors are preferred since high humidity can create noise in the measuring circuit leading to inaccurate readings.
