"gel box"

Multi-purpose monitoring electrodes with sticky gel feature a high performance adhesive and foam backing.

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.

The Go Direct Calcium Ion-Selective Electrode (ISE) can be used to measure the concentration of calcium (Ca²⁺) in aqueous samples.

Use the Go Direct Glass-body pH to measure pH in aqueous, heterogeneous, and organic solutions.

Use the Go Direct® Tris-compatible flat pH sensor to measure the pH of a solution or semisolid, such as food or soil.

The Go Direct Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of ammonium (NH₄⁺) in aqueous samples.

Oakton offers a variety of pH electrodes for your general purpose and speciality laboratory applications.

The Tris-Compatible Flat pH Sensor measures the pH of a solution or semisolid.

Use this sensor for weather studies, monitoring greenhouses, or for determining days when static electrical discharges could be a problem.

Measure concentration of ammonium in aqueous samples.

Measure the concentration of calcium in aqueous samples.
