Hanna HI5222-03 Research Grade pH/ISE/ORP Meter only

Hanna HI5222-03 Research Grade pH/ISE/ORP Meter only

The Hanna HI5222-03 Research Grade pH/ISE/ORP Meter only is a premium research-grade benchtop meter engineered for precise measurement of pH, ion-selective electrodes (ISE), and oxidation-reduction potential (ORP). Built for high-performance laboratory environments, this model offers exceptional accuracy, multi-parameter support, and full GLP compliance—all in a compact, user-friendly format. As the “meter only” version, it is ideal for users who already have compatible electrodes and probes.

Features

• Triple Measurement Support
  Measure pH, ORP, and ion concentration (ISE) with a single instrument—ideal for multi-parameter testing and lab standardization.

• High Accuracy and Resolution
  Delivers high-resolution readings with selectable pH resolution up to 0.001, and ISE resolution down to 0.001 concentration units, with accuracy as tight as ±0.002 pH and ±0.5% for monovalent ions.

• Multi-Point Calibration for Both pH and ISE
  Includes automatic 5-point calibration capability using 8 standard pH buffers and 5 customizable ones. ISE calibration supports 5-point calibration with fixed and user-defined standards.

• Built-In Logging System
  Stores up to 100,000 data points per channel, organized into 100 lots of 50,000 records. Logging modes include automatic, manual, and AutoHOLD with 14 interval presets from 1 second to 180 minutes.

• GLP-Compliant Calibration Records
  Tracks and stores detailed calibration data including timestamps, slope, offset, buffer/standard used, and probe details.

• Customizable Color LCD Display
  High-resolution 240 x 340 pixel color graphic display allows for real-time graphing, multi-view modes, and simple navigation.

• USB PC Connectivity
  Effortless data transfer for digital recordkeeping, reporting, and analysis.

• Temperature Compensation
  Automatic or manual compensation for pH readings from -20.0°C to 120.0°C, ensuring consistency across varying sample conditions.
