Pays for itself by speeding up batch sampling and reducing probe breakage. NASA Space Shuttle engineering assures smooth and effortless operation. Performs like a robot arm in zero gravity.

Fingertip control raises, lowers, and pivots (360 degrees) 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 electrodes always remain vertical.

It is designed to accept any standard glass, reference, combination or other pH electrode or conductivity probe, plus temperature probe. Weighted die-cast metal base and spring counterbalance permit fluid movement with superior stability. Beware of cheap, plastic look-a-likes that have jerky, uneven motions. Complete with 21 inch metal arm, 8 inch diameter metal base, and probe holder. Weight is 6 pounds.
