  • FC2023 Food Electrode: Conical tip for direct penetration into solids & semi-solids
  • Open Junction Design: Clog-resistant viscolene reference for stable readings
  • Automatic Temperature Compensation: Accurate results from -5 to 105°C
  • Portable & Waterproof (IP67): Durable, compact design with long battery life

Description

The HI99161 Food and Dairy pH Meter is engineered to deliver reliable pH measurements across a wide range of food products, including dairy, meats, processed foods, and beverages. It comes equipped with the FC2023 pre-amplified pH electrode, specifically designed for food applications. The conical glass tip allows easy penetration into solids and semi-solids such as cheese, yogurt, and meat, ensuring direct and accurate readings. Its open junction reference system, utilizing viscolene gel, prevents clogging and contamination while maintaining rapid response and stability.

Constructed with a durable PVDF food-grade body, the FC2023 electrode resists chemicals, abrasion, UV exposure, and fungal growth, making it suitable for demanding food production environments. The meter features automatic one or two-point calibration, a probe condition indicator (CAL Check), and automatic temperature compensation for precise readings in varying conditions. With waterproof IP67 protection, long battery life (up to 1400 hours), and a user-friendly HELP function, the HI99161 offers dependable performance for food safety and quality control professionals.
