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 reference chamber.
This product comes with a small container of buffer solution. Fill the sensor cap with the buffer solution and let it soak between uses.
This probe connects to the BNC connector on our pH interface boards. See the Connection & Compatibility tab for a complete list of options.
This ORP electrode creates a voltage differential that can be read by one of our pH/ORP interfaces:
