Fisherbrand™ accumet™ Polymer Membrane Combination ISEs, Mercury-Free: Nitrate

Description

• Fast, precise measurements in aqueous solutions over a wide range of concentrations
• 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 Features 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 Dimensions Diameter: body, 0.5 in
