FC231D 'Intelligent Electrode' for Meat Products

Intelligent pH Electrode for Meat Products

The FC231D is a specialised electrode designed for use in the food industry. It is suitable for pH measurement of meat products and can be fitted with two different knife blades.

This electrode is supplied complete with a 1m white food cable and 7-pin DIN connector.

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 FC231D is suitable to use with samples that measure from 0 to 50°C.

PVDF Body

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.

DIN Connector

The FC231D Smart pH electrode has a DIN connector that can only be used with the HI-98140, HI-98150, HI-98230, and H-I98240 portable meters.

Built-In Microchip

The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition, and buffers used. This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot swapping of probes without having to recalibrate. All pH measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analogue measuring system. Electrical noise can be generated from a built in temperature sensor and while working in a humid environment.
