Hanna HI5522-02 Professional benchtop pH/ISE/EC

Hanna HI5522-02 Professional Benchtop pH/ISE/EC Meter

The Hanna HI5522-02 Professional benchtop pH/ISE/EC is a high-performance, research-grade benchtop meter designed for advanced electrochemical measurements, including pH, ISE (Ion-Selective Electrodes), EC (Conductivity), TDS, resistivity, salinity, and mV. Engineered for flexibility, compliance, and accuracy, the HI5522-02 is ideal for laboratories in pharmaceutical, environmental, and industrial sectors.

Features

• Multi-Parameter Measurement Capability
  Simultaneously measures pH, ion concentration (ISE), conductivity (EC), total dissolved solids (TDS), resistivity, salinity, and mV, offering exceptional analytical flexibility.

• High-Accuracy Performance
  Delivers outstanding resolution and accuracy with up to ±0.002 pH, ±0.2 mV, and ±0.5% for monovalent ions, ideal for critical applications.

• Advanced Calibration Options
  Supports 5-point calibration for both pH and ISE with eight standard and five custom buffer/standard solutions. EC calibration includes auto-recognition and user-defined values.

• USP Compliance
  Fully compliant with USP <645> conductivity testing, making it suitable for pharmaceutical-quality water monitoring.

• Dual Input Channels & Profile Storage
  Operate two channels independently and save up to 10 user profiles (5 per channel) for quick access to saved configurations.

• Flexible Temperature Compensation
  Choose from disabled, linear, or non-linear (natural water) temperature compensation modes, with configurable coefficients and reference temperatures.

• Calibration Reminders & GLP Support
  Built-in reminders help maintain calibration integrity. GLP functionality tracks calibration data, including time, date, offset, and slope.
