This pH electrode is a plastic body, double junction, gel filled pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design.

This electrode storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. Properly storing your pH electrode in a solution keeps the glass membrane well hydrated which maintains proper function and provides accurate readings.

Lightweight, Versatile Unit

These durable TDS testers feature a replaceable electrode and are ideal for student use in the classroom and field environments.

The double junction electrode is ideal for dirty water, heavy metals, sulfides, tris buffers, and organics. The tester also features a pH and temperature readout toggle, automatic temperature compensation, and a replaceable sensor.

Compact and easy to use-ideal for students to learn the basics of pH in the classroom.

Multi-parameter meters engineered for student use in real world testing environments.

With a long-lasting design, these 2-in1 testers are a smart choice for student experiments in both the classroom and field applications.

The HALO2 Wireless General Use pH Tester has a refillable glass body and spherical glass sensing bulb made for users that prefer a low-maintenance laboratory-grade pH electrode.
