Frequently Asked Questions

What is the EXTECH RE305 electrode used for?

The EXTECH RE305 is an ORP (oxidation-reduction potential) electrode used to measure the cleanliness or contamination level of water in industrial processes, wastewater treatment, and laboratory testing. It delivers readings from -999 to 999mV ORP with a flat tip for surface or drop measurements.

What are the specifications of the EXTECH RE305?

The EXTECH RE305 is a single-junction ORP electrode with a range of -999 to 999mV ORP. It features a flat tip shape, polycarbonate material, a proprietary connection type, and an overall diameter of 5/8 in. The manufacturer part number is RE305.

Where to buy the EXTECH RE305 worldwide?

3G Electric supplies the EXTECH RE305 electrode worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time; we source and deliver this ORP electrode to any country.

How to maintain the EXTECH RE305 ORP electrode?

To maintain the EXTECH RE305, rinse the flat tip with distilled water after each use and store it in a storage solution or moist environment to prevent the single junction from drying out. Avoid mechanical shock to the polycarbonate body. Calibrate periodically with standard ORP buffer solutions.
