Ohaus has gone beyond weighing!
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.
The STDO11 is a galvanic DO electrode with a plastic shaft that produces its own electric current. The cathode is silver and the anode is zinc. Oxygen passes through the membrane and is reduced at the cathode to increase the electrical signal (current) read by the electrode. As oxygen increases, the signal increases. Galvanic sensors are active at all times and will degrade in storage as well as during use. They do not need to polarize (warm up) before calibration or measurement while polarographic electrodes take 15 minutes to several hours to warm up.
The STDO21 electrode includes a temperature sensor.
