Speeds up batch sampling and reduces probe breakage. Ideal for multiple conductivity or pH readings. Fingertip control raises, lowers, and pivots (360°) the perfectly balanced electrode holder wherever desired. Moves in all directions, holds electrodes safely and securely in any selected position. Electrode arm articulates at three points so the electrodes always remain vertical. It is designed to accept any standard glass, reference, combination or other electrode-a temperature probe or conductivity probe. Weighted die-cast metal base and spring counterbalance permit fluid movement with superior stability. Complete with 21" metal arm, 8" diameter metal base, and probe holder. Weighs six lbs.
