The new pH electrodes line 870 combines a tough ryton body with auto-cleaning flat pH surface and with a reliable Pt1000 for an accurate measurement in dirty liquid as well as in aggressive solutions. In addiction a wide junction improves performances in presence of suspended solids. The new 870 electrodes allow a direct installation by their ¾” threaded included in the body: in-line installation using the threads on the electrode bottom or submersible installation using the threads on the electrode head. Availability of specific versions for special applications as: horizontal mounting (-HM), low conductive samples (-LC), aggressive solutions (HF<2%)/low values of pH (-HF).
