  • 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:
