Smart Foodcare pH Electrode for Meat and Semi-Frozen Products - FC231D

A$435.60

The FC231D is an amplified single junction pH electrode that has a built-in temperature sensor and connects to the meter with a DIN connector. The DIN connector of this electrode can be used with the HI98140, HI98150, HI98230, and HI98240 portable meters.

The FC231D electrode features a built-in microchip that stores sensor type, serial number, and calibration information. It also features an open junction design, a sensing bulb made of low temperature glass, and a built-in temperature sensor. This Smart electrode has a DIN connector that can only be used with the HI98140, HI98150, HI98230, and HI98240 portable meters.

This design consideration is ideal for pH measurements in meat and semi-frozen food samples. The recommended operating temperature range is from 0 to 50°C.

open junction

Open Junction

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 FC231D uses low temperature (LT) glass, conical bulb, food grade PVDF body, and open junction with viscolene gel electrolyte.  

low temperature glass

 

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.   

conical tip

 

 

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 meat penetration blade

 

 

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 FC231D.

pvdf body

   

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

 

 

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

 


DIN Connector

The FC231D Smart pH electrode has a DIN connector that can only be used with the HI98140, HI98150, HI98230, and HI98240 portable meters.

built in microchip

 


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 analog measuring system. Electrical noise can be generated from a built in temperature sensor and while working in a humid environment.
