VWR* pH Electrode Arm
Just a touch of the finger helps provide multiple pH readings quickly and efficiently. Electrode arm moves in almost any direction, holding up to three electrodes safely and securely in selected positions. 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.
