Double-Junction Electrode

Double-Junction reference electrodes are designed with two junctions and two reference solutions.

Junction II will not contact test solutions so that junction II will be hardly contaminated by test samples, which in turn maintains a more stable test performance.

Additionally, reference solution does not contain silver ion, which can significantly reduce junction clogging

Start with the customer – find out what they want and give it to them.

Revolutionary Blue-Gel Inner Solution

The inner solution in pH electrode's glass bulbs are typically in liquid form, which generate air bubbles from time to time during usage. If not removed properly, the air bubble could cause inaccurate and unstable measurements.

The 60-Z series pH electrodes adopt a uniques blue-gel inner solution, which would not flow and never generates air bubbles. The meter can function well even when being placed upside down.
