Products for USB Sensing and Control
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 1 meter cable terminated by a BNC connector.
When you receive this sensor, fill the cap with buffer solution and ensure that it has no leaks.
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:
