Product information "FC2100 Edge Electrode - Digital pH/Temperature Electrode for Dairy (Glass Body)"

The FC2100 is a digital glass body, gel filled pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design. This probe connects to the meter with a 3.5 mm connector. The 3.5 mm connector is proprietary to meters that use digital electrodes.


The FC2100 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 milk, yogurt, cheese, and other products in the dairy industry. The recommended operating temperature range is from 0 to 60°C.

digital electrode

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 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 including meat, cheese, yogurt, and milk. The FC2100 utilizes general purpose (GP) glass, 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

Open Reference Junction

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 (viscolene) interface 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.


glass body

Glass Electrode Body

The glass electrode body is suitable for a wide range of applications due to its chemical resistance. The glass electrode is compatible with many non-aqueous solvents and other aggressive chemicals. Glass is also resistant to many forms of radiation, such as ultraviolet radiation.
