Electrode arm moves in almost any direction, holding up to three electrodes safely and securely in selected positions.

  • Ideal for multiple pH readings
  • Accepts all standard electrodes
  • Pivots 360°, Extends 53 cm (207/8")
Fingertip control raises, lowers, and pivots the holder. The arm articulates at the three points to maintain electrodes in vertical position.

Designed to accept any standard glass, reference, combination, or other electrode — even a temperature compensation probe. Weighted base and spring counter-balance permit smooth, fluid movement with superior stability.
