Hanna HI4013 Nitrate Half-Cell Ion Selective Electrode

Hanna HI4013 Nitrate Half-Cell Ion Selective Electrode (ISE)

The Hanna HI4013 Nitrate Half-Cell Ion Selective Electrode is a high-performance nitrate ion selective electrode (ISE) that uses a polymer membrane half-cell design to deliver accurate, selective measurement of free nitrate ions (NO₃⁻) in a variety of sample types. This electrode is ideal for users who need fast, repeatable nitrate measurements in both field and laboratory settings, especially in environmental and agricultural applications.

Key Features

• Wide Measurement Range: The HI4013 covers concentrations from 1.0 M to 1×10⁻⁵ M, equivalent to 6200 to 0.62 mg/L (ppm) nitrate or 1400 to 0.4 mg/L (ppm) as nitrogen (N). This range ensures reliable detection of both high and trace nitrate levels.

• Robust Half-Cell Design: Built with a polymer membrane, the half-cell configuration requires a separate reference electrode, allowing for more flexible and stable measurements.

• Optimized pH Range: Operating best between pH 3.0 and 8.0, the electrode performs reliably across common water and food sample conditions.

• Temperature Stability: Designed for use between 0 to 40°C, it provides dependable results under most laboratory and field environments.

• Durable Construction: The epoxy and PVC body offers excellent chemical resistance and mechanical strength, making it suitable for rugged use.

• Versatile Applications: Analysts frequently use the HI4013 to test freshwater, seawater, plant tissue extracts, and emulsified food products for free nitrate content.

• Standard BNC Connection: The 1-meter coaxial cable terminates in a BNC connector, ensuring compatibility with most ion meters and pH/mV meters.
