Hanna HI4009 Ion-Selective Electrode for cyanide measurement with solid-state half-cell technology and epoxy body.
Hanna HI4009 Ion-Selective Electrode for Cyanide is a laboratory-grade, solid state half-cell designed for the accurate detection of cyanide ions (CN–) in solution. The HI4009 features a silver halide sensing pellet that ensures exceptional selectivity and response by enabling ion exchange at the electrode membrane-sample interface. Encased in a rugged, chemical-resistant epoxy body with a convenient BNC connector, this electrode suits routine and demanding analyses alike.
Applications include use in microelectronics, plating industry, environmental and wastewater monitoring, and agriculture where trace-level cyanide quantification is critical. The HI4009 delivers high sensitivity and selectivity in industrial, laboratory, and field settings.
