FC2320

Description

The FC2320 is a digital PVDF body, gel filled pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments edge® Tablet Meters.The FC2320 electrode features a built-in microchip that stores sensor type, serial number, and calibration information. It also features an open junction design with viscolene gel electrolyte, a sensing bulb made of low temperature glass, and a conical tip shape. This design consideration is ideal for pH measurements in samples such as meat and semi-frozen food samples. The recommended operating temperature range is from 0 to 60°C.

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.

  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 including
meat, cheese, yogurt, and milk.
•  The FC2320 utilizes Hanna’s general purpose (GP) glass formulation, which has a resistance of approximately 100 megaohms. This means that measuring
conditions are optimal around ambient temperatures.
•  Use of high temperature or low temperature glass around ambient temperatures would not be optimal due to a long response time or a shortened lifespan of the electrode.

  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 glass 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.

  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.

  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 FC2320.
