Cheese production relies heavily on precise pH measurements from milk to maturation. The acidification process, rennet efficiency, curd firmness, brining balance, and microbial aging all depend on maintaining exact pH ranges. Even minor deviations can result in spoilage, structural defects, or unwanted bacterial interference.

Whether monitoring whey pH during drainage or evaluating finished ripened products, the HI98165 is engineered for dependable accuracy in semi-solid dairy environments. The supplied FC2423 electrode is tailored for cheese testing, featuring a rugged stainless steel body, clog-resistant open junction, and quick-connect DIN design for seamless waterproof integration.

FSMA Compliant

This pH meter meets the FDA Food Safety Modernization Act (FSMA) compliance standards.

The FC2423 electrode is purpose-built for the demanding conditions of cheese testing, from soft curds to aged hard cheeses. Its durable stainless steel sheath penetrates semi-solids without damaging the product, while the conic glass tip ensures stable surface contact for reliable pH readings.

Stainless Steel Body

AISI 316 stainless steel resists corrosion in dairy environments and ensures long-term durability during field and in-plant use.

Conic Glass Tip

Optimized for semi-solid contact, the cone-shaped tip allows deep insertion into cheese samples without compromising structure.

Built-In Temperature Sensor

Eliminates calibration errors by automatically compensating for temperature fluctuations during measurement.

Hanna’s CAL Check™ diagnostic system proactively ensures measurement reliability, alerting users to electrode issues, contamination, or outdated buffers during calibration. A post-calibration percentage score indicates probe health, factoring slope and offset data for transparent performance tracking.

The AutoHold feature freezes a stable measurement automatically, minimizing human error. When working within production-specific calibration ranges, an optional out-of-range warning further protects batch consistency.

Users can log and store up to 200 measurement entries, each paired with full GLP metadata including calibration time, offset, and slope. Data can be recalled on screen or transferred via USB for secure recordkeeping.

Integrated contextual help is available via a dedicated key, providing tailored support for each screen—ideal for field users or multi-lingual teams.

A backlit graphic LCD ensures clarity in dark storage areas or bright processing rooms, while intuitive button placement and multilingual support streamline user operation.

The rugged HI720165 carrying case holds all necessary accessories for mobile pH testing, including meter, electrode, beakers, buffer packets, and cleaning solutions.
