Hanna Instruments Electrode Holder with Steel Base

Hanna Instruments HI76405 Benchtop Electrode Holder with Heavy Steel Base

The Hanna Instruments HI76405 Electrode Holder is a heavy-duty benchtop stand designed to secure multiple analytical probes, electrodes, and temperature sensors during laboratory testing. Featuring a weighted steel base for maximum stability, the HI76405 prevents accidental tipping and sensor damage during routine pH, conductivity, dissolved oxygen, and oxidation-reduction potential (ORP) measurements. The adjustable flexible arm and articulated head assembly permit smooth vertical and horizontal positioning, enabling precise placement of probes into sample beakers, volumetric flasks, or testing vessels. Engineered to accommodate up to five standard 12 mm laboratory electrodes simultaneously, this holder reduces mechanical strain on probe cables while streamlining multi-parameter electrochemical analysis across quality control, analytical research, and water quality testing laboratories.

Technical Performance & Structural Attributes

• Heavy-Duty Weighted Steel Base: High-density steel base plate provides a low center of gravity, preventing movement or tipping during multi-probe immersion.
• Multi-Probe Articulated Arm: Holds up to five standard 12 mm diameter sensors, probes, or temperature sensors simultaneously for high-throughput testing.
• Smooth Height & Angle Adjustment: Counterbalanced articulated arm permits effortless vertical motion and angular alignment without binding or slipping.
• Corrosion-Resistant Protective Finish: Chemical-resistant surface coating protects the metal base and mounting hardware from acid, base, and salt solution splashes.
• Cable Routing Management: Integrated cable clips secure sensor wires along the support arm, keeping the benchtop organized and eliminating cable drag.
