SenTix® 82 and 81

The SenTix® 82 is one of the most popular electrodes on the market. These probes are ideal for most makes of bench-top pH meters, thanks to its common BNC style plug, and suitable for a wide range of applications; so much so that you could call the SenTix® 82 electrode the “universal electrode”.

The SenTix® 81 electrode is the identical, but uses a DIN style connection. 

The "universal electrode"

SenTix® 82 electrodes are one of the most robust glass probes available thanks to being constructed from industry leading SCHOTT® glass. A platinum junction provides laminar flow of electrolyte solution, allowing fast reaction as well as reducing the chance of blocking and therefore extending the life time of the electrode. Compatible with Tris buffers.

  • Acids
  • Beer
  • Beverages
  • Coffee extract
