OMEGA Engineering is pleased to offer a complete line of laboratory pH electrodes. The PHE-4200 Series are gel-filled, combination pH electrodes with a unique clear epoxy body design. With five electrode styles to choose from, you’re sure to find one suitable for your application. OMEGA ® PHE-4200 electrodes offer reliable quality at a reasonable cost. The electrodes measure the entire pH range from 0 to 14 pH units at 0 to 100°C (32 to 212°F) and feature an Ag/AgCI reference and polypropylene liquid junction. Each electrode comes in a soaker storage bottle to keep the electrode moist and ready for use. Shelf life is guaranteed for one year, and the OMEGA quality certificate provided assures that these electrodes meet the most stringent quality control requirements.

Are there any installation arrangement requirements to be aware of? Does entire length need to be submerged? Does orientation matter?

Asked by: Trevor
Thank you for your question? pH probes should be mounted vertically or at least 15deg above the horizontal plane in the direction of flow. At a minimum the bulb at the end of the probe needs to be fully submerged for an accurate reading.

Will this probe work in D ionized water?

Asked by: Mary
Thank you for your inquiry. We would recommend the PHE-4202-LC for DI water. It is the same as the PHE-4202 but for low conductivity fluids. This will be a custom probe so please contact us at for price and lead time.
