Foodcare pH Electrode for Meat Products with Quick Connect DIN Connector$225.00
The FC2323 is an amplified single junction pH electrode that has a built-in temperature sensor and connects to the meter with a quick connect DIN connector. This type of connector is proprietary to specific meters such as the HI98190. The FC2323 electrode features a food grade plastic PVDF body, an open junction design with viscolene gel electrolyte, a sensing bulb made of low temperature glass, and a conical tip shape. This design consideration, along with the optional stainless steel blades, is ideal for pH measurements in meat and semi-frozen food products. The recommended operating temperature range is from 0 to 50°C.

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.
The FC2323 uses low temperature (LT) glass, conical bulb, food-grade PVDF body, and an open junction with viscolene gel electrolyte.
Low-Temperature Glass Formulation
The glass tip uses a special LT glass formulation with a lower resistance of approximately 50 megaohms compared to general-purpose (GP) with a resistance of about 100 megaohms. This is beneficial since many food products are stored at low temperatures. As the temperature of the glass decreases in the sample, the resistance of the LT glass will increase approaching that of GP glass at ambient temperatures. If using GP glass, the resistance would increase above the optimum resistance for the high impedance input of a pH meter. The FC2323 is suitable to use with samples that measure from 0 to 50°C.
Conical Glass Tip
The conical-shaped tip design allows for penetration into solids, semi-solids, and emulsions for the direct measurement of pH in food products.
Stainless Steel Blade
An optional stainless steel blade is attached to the probe for easy meat penetration, even in frozen samples. Slicing into the meat will allow for the pH glass and reference junction to be in contact with the sample, allowing for a direct pH measurement without extensive sample preparation. The FC098 (20 mm; 0.75”) and the FC099 (35mm; 1.38”) are a set of two stainless steel penetration blades to be used with the FC2323.
Polyvinylidene fluoride (PVDF) is a food-grade plastic that is resistant to most chemicals and solvents, including sodium hypochlorite. It has high abrasion resistance, mechanical strength, and resistance to ultraviolet and nuclear radiation. PVDF is also resistant to fungal growth.
Open Junction Reference
Suspended solids and proteins found in food products will clog a conventional ceramic reference junction. This clogging will impede the measurement circuit between the indicating electrode and the internal reference resulting in slower response time, erratic readings, and frequent electrode replacement. The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable readings.
Quick Connect DIN Connector
The FC2323 uses a Quick Connect DIN connector that makes attaching and removing the probe simple and easy. This type of connector is proprietary to the meter. See specifications table for compatible meters.
