"Complete Meter Stick Optics Bench"

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.

Bidirectional angle sensor.

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

This spare pH sensor makes electrode replacement quick and easy. The spare pH sensor is designed as an easy-fit cartridge that locks into place, featuring two o-rings to maintain a watertight seal. With no pins to line up or that can break, this sensor is ideal for quick replacements.

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

Easily collect motion data without the need for additional interfaces.

Measure the ability of a solution to act as an oxidizing agent or reducing agent with this oxidation-reduction potential sensor.

General-purpose pH Sensors can be used across disciplines, with applications in chemistry, biology, middle school science, and environmental science.
