The FC201D is a PVDF body, gel filled, single junction, Smart pH electrode with a DIN connector. The FC201D 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 the food industry including dairy, dough, ground meats, and other semi-solid food samples. The recommended operating temperature range is from 0 to 50°C. 

  • Low Temperature Glass
  • 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 smart pH electrode FC201D uses low temperature (LT) glass, conical bulb, food-grade PVDF body, and 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 FC201D 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 including meat, cheese, yogurt, and milk.


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 FC201D Smart pH electrode has a DIN connector.

Smart Electrode with Built-In Microchip

The built-in microchip stores calibration information including date, time, offset, and slope. This information is automatically transferred to a compatible meter when the electrode is connected. The ability to transfer information allows for swapping of probes without having to recalibrate.
