"pH Meters and Supplies"

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

Easy to carry, simple to operate and sufficient for most field pH tests.

The Neutralization by the Drop Titration Method Kit contains an easy and hands-on titration experiment.

Store Up to 15 Readings

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 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.

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.
