Description

The SenTix® 81-87 pH electrodes with their high-quality glass shaft and refillable 3 mol/l KCl liquid electrolyte and platinum diaphragm are suitable for demanding measurements in the laboratory. The platinum wire diaphragm offers optimum electrolyte flow without clogging and the liquid electrolyte offers fast response times. The electrodes can also be used in difficult samples. The cone shape of the membrane is impact-resistant and easy to clean. These electrodes have different temperature sensors (see table “Connections & variants”).

The SenTix® 81-87 are particularly suitable for the following applications:

Chemical:	Industrial:
Diluted acids Emulsions/suspensions	Cooling water, dyeing solutions, electroplating baths Paper extract
Water & Environmental:	Beverages:
Saline solutions Swimming pool water Groundwater Lake water, surface water, sea water Drinking water Soil extract	Beer, soda/lemonade Fruit juice, vegetable juice, wine Mineral water Milk
Cosmetics & Cleaning:	Food:
Hair color Mouthwash Household cleaners	Coffee extract Vinegar
Pharma, Medical, Bio:
Enzyme solutions, gastric juice, infusion solutions, protein-containing liquids, serum, tris buffer solutions, urine

The SenTix® 81-87 are available in various versions with different plugs and temperature sensors:
