ARS-Z Gel-Filled ORP Combined Electrode

Brand: KOBOLD Instruments, Inc.

The ARS-Z Gel-Filled ORP Combined Electrode for general pH measurements is filled with KCl gel (0% silver ions) and contains a salt distillate, which ensures longer stability times. The discharge system Ag/AgCl has been designed as a cartridge.

The combined electrode version with PTFE ring diaphragm is especially suitable for tough service conditions, for example, service in clarification plants or in oily and very soiled media.

A temperature sensor Pt-100 can be integrated (SMEK screwed head conduit thread 13.5 version). The electrode can resist pressure up to 10 bar. Its dimensions are 120 x 12 mm (DIN 19 263).
