VWR® pH Electrode Arm

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")

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.
