The Radiometer PHC3131-9 Combination pH Electrode has a glass body, Ag/AgCl reference system, non-refillable gel electrolyte (3M KCl) and open junction. The PHC3131-9 has a spear shaped sensor for penetration applications. The PHC3131-9 is a screw cap electrode and requires the CL114 cable (part no. A94L114) for compatibilty with Hach Sension+ laboratory pH meters (or any meter with a BNC connection).
To meet your analysis needs, Radiometer Analytical electrodes are available with a variety of lengths, diameters and reference systems. There is a Radiometer electrode for every application.
Radiometer Analytical glass pH electrodes are made with highly shock-resistant glass, making them extremely tough. The average lifetime of a correctly maintained Radiometer glass pH electrode is approximately two years.
