A lead wire connecting the platinum electrode passes through the glass tube for external connections, so that only the platinum electrode comes in contact with the electrolyte. Packed in a Styrofoam case. Mounted on a cast iron stand designed for safe clamping. Requires a 6V battery or low voltage DC power supply for operation (not included).
