Ohaus® Starter Reference Electrodes
By Ohaus
To complement the Ohaus® Starter Series, a full offering of electrodes is provided that will accurately test for a variety of measurement types that include pH, Conductivity (EC), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Oxidation Reduction Potential (ORP) and Salinity.
Reference eletrodes have a stable and well defined electrochemical potential. A measured potential in an electrochemical cell is determined against a defined potential value of a reference electrode. STREF2 is saturated calomel electrode (SCE)(Hg/Hg2Cl2 in saturated KCl) which traditionally is the most widely used electrode. The disadvantage is that it cannot be used above 50°C due to Hg2Cl2 instability. STREF1 is Silver/Silver Chloride (Ag/AgCl in Saturated KCl), which represents another type of reference electrode.
- Sturdy and durable electrodes are constructed of glass shafts and built to withstand daily use.
- Electrodes fit perfectly in the electrode holders on Ohaus® bench meters and electrode clips on all Ohaus® portable meters.
