Hanna HI5222-02 Research Grade pH/ISE/ORP Meter

Hanna HI5222-02 Research Grade pH/ISE/ORP Meter

The Hanna HI5222-02 Research Grade pH/ISE/ORP Meter is a research-grade, dual-channel benchtop meter designed for high-precision measurements of pH, ISE (ion concentration), and ORP (oxidation-reduction potential). Engineered for demanding laboratory environments, this instrument combines exceptional measurement performance, GLP compliance, and user-friendly features, including a vivid color graphic display and robust data logging capabilities.

Features

• Triple Measurement Capability
  Capable of measuring pH, ISE, and ORP in one system, providing unmatched flexibility for advanced laboratory testing.

• High Accuracy and Resolution
  Achieve precise readings with selectable resolution up to 0.001 pH, 0.001 ion concentration, and 0.1 mV, with accuracy as high as ±0.002 pH and ±0.5% for monovalent ions.

• Multi-Point Calibration for pH and ISE
  Up to five-point automatic calibration for both pH and ISE, with built-in standards and customizable buffer/standard options.

• Advanced Logging Capabilities
  Stores up to 100,000 data points per channel, with 100 lots (50,000 records per lot), and selectable logging intervals from 1 second up to 180 minutes.

• GLP Compliance
  Tracks all critical calibration and measurement metadata, including calibration points, time stamps, slope, probe offset, and standard/buffer values used.

• Dual Sensor Inputs
  Supports simultaneous measurements from two input channels (e.g., pH/ORP + ISE), streamlining laboratory workflows.

• Color Graphic LCD
  A bright, high-resolution 240 x 340 pixel color LCD provides intuitive navigation, real-time graphing, and on-screen help.

• Included High-Quality Probes
  Comes with a HI1131B glass-body pH electrode and a HI7662-T stainless steel temperature probe, each with a 1-meter cable.

• USB PC Connectivity
  Easily transfer data to your computer for further analysis and documentation.
