Hanna HI4009 Cyanide Half-Cell Ion Selective Electrode

Hanna HI4009 Cyanide Half-Cell Ion Selective Electrode

The Hanna HI4009 Cyanide Half-Cell Ion Selective Electrode is a solid-state half-cell ion-selective electrode (ISE) specifically designed for the direct measurement of cyanide ions (CN⁻) in aqueous solutions. This electrode provides fast, accurate, and selective detection, making it ideal for industrial process control, environmental testing, and regulatory compliance in laboratories. It requires use with a separate reference electrode to complete the measurement system.

Key Features

• High Sensitivity to Cyanide Ions
  Measures cyanide concentrations from 10⁻² M to 1 × 10⁻⁶ M, equivalent to 260 ppm to 0.02 ppm, ensuring both high and trace-level detection.

• Solid-State Technology
  Features a long-lasting solid-state membrane, offering a typical slope of –57 mV/decade for accurate linear response.

• Alkaline Operating Conditions
  Designed to function effectively in high pH environments (pH > 11), which is essential for cyanide stability in solution.

• Robust Epoxy Body for Tough Environments
  Constructed with a 12 mm diameter epoxy body and 120 mm insertion length, it withstands chemical exposure and routine lab handling.

• Universal BNC Connector
  Comes with a 1-meter coaxial cable and standard BNC connector, compatible with most pH/ISE meters.
