Hanna HI98164 Professional Portable Yogurt pH Meter – Precision pH Analysis for Dairy and Fermented Products

The Hanna HI98164 Professional Portable Yogurt pH Meter is a robust and high-precision portable pH meter designed specifically for measuring the pH of yogurt and other viscous, semi-solid fermented dairy products. Featuring the specialized FC2133 PVDF-body pH electrode, this meter ensures fast, stable, and accurate measurements even in challenging samples such as thick yogurt or creamy dairy blends.

With waterproof construction, automatic temperature compensation, flexible calibration, and data logging capability, the HI98164 is the trusted solution for dairy laboratories, quality assurance, and on-site production monitoring.

Key Features

• Designed for Yogurt and Semi-Solid Dairy Samples
  Supplied with the FC2133 Foodcare PVDF-body pH electrode with built-in temperature sensor and quick-connect DIN connector, ideal for creamy and viscous samples.

• High-Resolution pH and mV Readings

  • pH Range: –2.000 to 20.000

  • Resolution: 0.1 / 0.01 / 0.001 pH

  • Accuracy: ±0.1 / ±0.002 pH

  • mV Range: ±2000 mV with ±0.2 mV accuracy
