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
