    Preassembled, pretested membrane/cap unit

    • Assures optimum membrane tension and alignment, with no-leak operation
    • Membrane is much less susceptible to surfactant deterioration: use it for extended periods in more varied solution types—wastewater samples, process streams
    • Noncrystallizing fill solution won't impede performance or cause membrane rupture
    • With 39 in. (1m) lead


    • Tough, chemical-resistant body
    • Bonded membrane/cap assembly
    • Continuous electrical shielding and insulation of internal elements, cable and connectors
    • Extremely stable, reproducible readings with a minimum of electrical noise
    • Lower detection limits than conventional ISEs
    • Rapid response time that lowers cost per test
    • Individually tested, serialized to meet GLP requirements, and backed by the Fisher Scientific™ Technical Applications staff

    Ammonia Combination ISE

    • Determines ammonia and ammonium ion concentration in diverse samples
    • Applications include sewage effluent, boiler water, industrial wastes, stack gases, food, fertilizers
    • Measurements are unaffected by sample color, turbidity or suspended solids
    • Gases such as CO2, SO2 and H2S do not interfere
    • Method has ASTM and EPA approval
    Carbon Dioxide Combination ISE
    • Measures carbon dioxide, carbonate and bicarbonate
    • Applications include carbonated beverages, wines, groundwater, seawater
