Sensor sealed in epoxy body

  • Sensing modules contain liquid internal filling solution in contact with gelled organophilic membrane
  • Membrane is impregnated with a selective ion exchanger for ion of interest
  • Sensors are sealed into durable epoxy body with built-in reference half-cell
  • Permit fast, precise measurements in aqueous solutions over a wide range of concentrations
  • Epoxy body provides chemical resistance
  • Tough, chemical-resistant epoxy body
  • Membrane assembly sealed to body
  • 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
  • Diameter: body, 0.5 in. (12.7mm); cap, 0.625 in. (16mm)
  • Length: body, 4 in. (10.2cm); cap, 1 in. (2.5cm); overall, 5 in. (12.7cm)

Calcium Electrode
