Triode pH Electrodes  

Measures pH and Temperature with One Electrode
All Orion Triodes have built-in temperature sensors allowing you to measure pH and temperature with one electrode. There are a variety of electrodes based on your sample and application. The ROSS Ultra Triodes offer such great stability and drift that the warranty period is double that of other electrodes.

  • The refillable electrodes have a two year replacement warranty
  • The gel-filled ROSS Ultra Triode electrodes have an 18 month warranty
  • Complex samples, such as biological media, foods and pharmaceuticals, can be measured easily
  • All ROSS Ultra electrodes can be used in samples that contain TRIS, sulfides or proteins
  • ROSS Ultra electrodes offer the best temperature performance of all other electrodes in repeated, varying temperatures
  • The AquaPro Triode has the advantage of having an open junction that does not clog and double junction reference
  • Ag/AgCl Triodes have good response and are ideal for routine measurements.
