What to consider: The more caustic an environment, the great impact on the electrode. Electrodes in cheaper entry-level testers can wear out quickly, especially if using them in environments with high levels of contaminating ions (or compounds). Disposable single-junction testers are ideal for occasional use. Single-junction electrode testers are appropriate for daily use in non-caustic environments. Double-junction electrode testers provide the longest-lasting use in the most caustic environments.
