Product Overview

FC202D is specifically designed for measuring milk pH and pH in semi-solid foods (including dairy products), making it an essential tool for kitchens or food laboratories. This pH electrode features a 1 m cable and a 7-pin DIN connector, and is designed for use with the HI99161 portable food and dairy pH meter.

• The PTFE body is easy to clean.

• Conical electrode tip for rapid penetration into food and dairy products.

• Ideal for small food and dairy operations as well as enthusiasts.

• Hanna Instruments offers a wide variety of pH electrodes for use in many different applications. The type of glass used to sense pH, bulb shape, body material, connection type, reference type, and electrolyte used are just some of the design considerations.

• FC202D is an amplified pH electrode with a built-in temperature sensor; ideal for measuring the pH of food. The probe features low-temperature (LT) glass, a conical bulb, a food-grade PVDF body, and an open junction design with viscolene gel electrolyte.

• Low-Temperature Glass Formulation

Compared to general-purpose (GP) glass with a resistance of approximately 100 megohms, the glass tip uses a special LT glass formulation with a resistance of approximately 50 megohms. This is beneficial because many foods are stored at low temperatures. As the temperature of the glass in the sample decreases, the resistance of LT glass will increase, approaching the resistance of GP glass at ambient temperature. If GP glass is used, the resistance will increase above the optimum resistance for the high-impedance input of the pH meter. FC202D is suitable for samples from 0 to 50°C.

• Conical Glass Tip

• The conical tip design allows penetration into solid, semi-solid, and emulsified samples for direct pH measurement in foods, including meat, cheese, yogurt, and milk.

• PVDF Body

• Polyvinylidene fluoride (PVDF) is a food-grade plastic that resists most chemicals and solvents, including sodium hypochlorite. It has high abrasion resistance, mechanical strength, and resistance to UV and nuclear radiation. PVDF also resists fungal growth.

• Open Reference

• Suspended solids and proteins found in food can clog traditional ceramic reference junctions. This clogging will impede the measurement circuit between the indicating electrode and the internal reference, resulting in slow response times, unstable readings, and frequent electrode replacement. The open junction design consists of a solid gel interface (viscolene) between the sample and the internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it less prone to clogging, resulting in fast response and stable readings.

• DIN Connector

• FC202D uses a DIN connector, which can only be used with the HI99161 portable pH/temperature meter.
