Description

The SenTix® 51-57 pH electrodes with their plastic shaft are suitable for mobile (field) pH measurement as well as for pH measurement in the laboratory in water and aqueous solutions. The cylindrical shape of the membrane and the ceramic diaphragm are robust. These electrodes are refillable and respond quickly due to the liquid electrolyte and have various temperature sensors (see table “Connections & variants”).

The SenTix® 51-57 are particularly suitable for the following applications:

Water & Environmental	Beverages:
Aquarium water Swimming pool water Lake water, surface water, sea water Drinking water	Fruit juice, vegetable juice, wine Mineral water

The SenTix® 51-57 are available in various versions with different plugs and temperature sensors:
