Lab Electrodes: APT Instruments

Lab Electrodes

These pH electrodes are made for use in the lab or the field. Built on a less rugged scale than industrial electrodes, these electrodes are ideal for most applications. Choose single junction for clean water applications and double junction for dirtier substances.

Don't forget your
ATC Probe

Epoxy Body General Purpose — These economical pH electrodes are a good way to measure pH in everyday applications. Their rugged epoxy housing makes these a little more hardy for your application.
High Grade Glass Refillable — These glass electrodes are ideal for testing dirty water in high grade lab applications. Choose from single or double junction.
Epoxy Long Life Refillable — Long life electrodes are easy to use and easy to clean. Clean out clogs instantly.
Penetration — Use this series of electrodes when testing semisolids. Choose from double or single junction.
Small Diameter — A smaller diameter pH electrode is a great choice for testing pH out of test tubes. These long skinny probes are an ideal choice for your application.
Flat Tip — Choose this pH electrode for testing flat surfaces such as paper or skin. Select from a variety of choices.
Submersible — If you need to test pH levels more than a couple of inches under water, you need a submersible pH electrode.
Calomel — Use these electrodes for testing pH levels where metals or proteins are prominent. They give a more accurate reading for such materials.
ISFET Electrodes — These electrodes use ISFET technology to measure pH in areas where glass electrodes can be harmful to a sample or environment.
ORP Electrodes — Oxidation Reduction Potential, or ORP, is an important measurement related to pH. Choose either single or double junction and platinum band or gold disk.
