47530 (without base) 47540 (with base) proGuide 47520 (without base) 47510 (with base) Novel electrode holder Designed to hold WPI biosensors and any standard pH electrode, the unique ProGuide allows the positioning of an electrode in small sample volumes without the need for a micromanipulator. The smooth mechanism easily moves an electrode side-to-side or up and down while keeping it at a constant vertical angle. The ProGuide Plus (shown at right) comes with a micrometer positioner which allows fine adjustment of 0.01mm in your samples.
