Product Features

This lab electrode measures the ORP of a solution and connects to the 1130 - pH/ORP Adapter.
Product Description

The 3555 is an economical single junction combination electrode ideal for your general-purpose applications in the lab or field. It has the impact-resistant qualities of an epoxy body.

The electrode uses a Teflon diaphragm with a large Pt ring section and provides a fast, stable response. The sealed, gel-filled design requires virtually no maintenance as there is no need to refill the KCL solution.

The 3555 measures 120 mm (length) x 12 mm (diameter), can withstand temperatures to 80°C and measures ORP levels from -1500 to +1500mv.

It comes with a 6 meter cable terminated by a BNC connector.
