Hanna Instruments – HI98161 Professional Foodcare Portable pH Meter

The HI98161 Foodcare pH Meter is a professional, portable meter designed for measuring pH in milk, dairy, meats, cheeses, fruits, and other food products. Its conical glass tip and PVDF body allow accurate readings in solids, semi-solids, and emulsions, while the open junction Ag/AgCl reference ensures fast, stable measurements. Automatic or manual temperature compensation provides reliable results across a wide temperature range. With GLP data, PC connectivity, and a long battery life, this meter is ideal for food labs and processing facilities.

  • Conical Glass Tip: Easy penetration into solids, semi-solids, and emulsions
  • Open Junction Reference: Fast, stable readings without contamination
  • PVDF Body: Durable, chemical- and microbial-resistant food-grade material
  • Advanced Features: Automatic temperature compensation, GLP, AutoHold, PC connectivity

 

Description

The HI98161 pH Meter is engineered for precision measurement in food applications, from dairy to meat, fruits, and beverages. Its FC2023 PVDF electrode with internal temperature sensor enables accurate readings over a wide pH range (–2 to 20 pH) with high resolution (up to 0.001 pH). The conical low-temperature glass tip is optimized for solids, semi-solids, and emulsions, ensuring reliable penetration and measurement in complex food matrices. The open junction reference with gel interface prevents clogging and contamination, allowing quick and stable readings for repeated measurements.

Designed for ease of use and laboratory integration, the meter includes an on-screen setup, contextual help, and CAL Check™ calibration guidance. Automatic or manual temperature compensation ensures accuracy across –20 to 120°C, and GLP compliance allows traceable, reproducible measurements. Data logging, opto-isolated USB connectivity, and 200-hour battery life make it perfect for food production lines, quality control labs, and field testing, while the IP67-rated casing ensures durability in wet or harsh environments.

Features

  • Contextual help at the press of a button
  • Five-point pH calibration with seven standard buffers and five custom buffers
  • Automatic Temperature Compensation (ATC)
  • Displays overall condition of the pH electrode after calibration based on the offset and slope characteristics
  • Calibration timeout to alert the user at a defined interval when the calibration has expired
  • AutoHold freezes displayed measurement reading when stable
  • GLP data including date, time, pH calibration buffers, offset, and slope
  • 200 hour battery life with battery level displayed on measurement screen
  • PC connectivity via a sealed opto-isolated micro USB and HI92000 software
