Hanna HI98197 Professional Resistivity meter

Hanna HI98197 Professional Resistivity Meter with Flow-Through Cell – High-Precision EC, TDS, and Salinity Monitoring

The Hanna HI98197 Professional Resistivity meter is a professional-grade, waterproof resistivity meter engineered for ultra-accurate measurements of resistivity, conductivity (EC), TDS, salinity, and temperature. Designed with a flow-through cell configuration, it enables real-time monitoring of flowing samples in water purification, laboratory, or pharmaceutical systems. With advanced autoranging, multi-point calibration, and USB data logging, this instrument is ideal for applications demanding high sensitivity and data integrity.

Key Features

• Wide Range, Autoranging Resistivity Measurement
  Automatically ranges from 1.0 Ω⋅cm up to 100.0 MΩ⋅cm, covering applications from industrial process water to ultrapure pharmaceutical water.

• Multi-Parameter Capability
  Measures resistivity, EC, TDS, salinity, and temperature in a single compact instrument—ideal for quality control and validation.

• High Accuracy and Resolution
  ±1% of reading accuracy across all parameters with resolution as fine as 0.001 µS/cm for EC and 0.01 ppm for TDS.

• Automatic Multi-Point Calibration
  Calibrate up to five points using any of the seven memorized standards: 0.00 µS/cm, 84.0 µS/cm, 1.413 mS/cm, 5.00 mS/cm, 12.88 mS/cm, 80.0 mS/cm, 111.8 mS/cm.

• Flexible Temperature Compensation
  Supports NoTC, Linear, and Non-Linear ISO/DIS 7888 modes with adjustable temperature coefficients from 0.00 to 10.00%/°C.

• Advanced Logging and Data Management
  On-demand and interval logging supported, with USB connectivity for data export and full GLP (Good Laboratory Practice) compliance.

• Rugged and Waterproof for Field Use
  IP67-rated waterproof casing, 100% RH tolerance, and compact design make it ideal for field or in-line system installations.

• Long Battery Life
  Operates up to 100 hours on 4 x AA batteries (25 hours with backlight).
