£183.25 (exc. VAT) £219.90 (inc. VAT)

The FC200S is a PVDF body, gel filled, single junction pH electrode with a screw connector. This probe features an open junction design, a sensing bulb made of low temperature glass, and a food grade plastic body.

This design 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.

FC200S Foodcare Kynar Body pH Electrode information

Hanna's extended description

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 FC200S uses low temperature (LT) glass, conical bulb, food grade PVDF body, and open junction with viscolene gel electrolyte.


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.


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.

Best electrode care for great results


Keep the electrode hydrated

Why – Drying out the electrode leads to drifting pH values, slow response times, and incorrect measurements.

Fix – “Revive” a dry electrode by submerging the bulb and junction in pH storage solution for at least one hour.


Rinse, do not wipe your electrode

Why – wiping the pH glass can produce a static charge which interferes with the pH reading of the electrode.

Fix – Simply rinse the electrode with distilled or deionised water (DI). Blot (do not rub) with a lint-free paper towel to remove excess water.


Store your electrode in storage solution

Why – Storing in deionised water (DI) causes ions to leach from the glass membrane and reference electrolyte resulting in a slow and sluggish response.

Fix – Store your electrode in storage solution.


Clean your electrode regularly

Why – Deposits can form on the electrode during use, coating the sensing glass. This can lead to erroneous calibrations and readings.

Fix – Clean the electrode using a specially formulated cleaning solution for pH electrodes – ideally one that’s developed for your application.






Calibrate often

Why – All pH electrodes need to be calibrated often for best accuracy.

Fix – The frequency of calibration depends on how accurate you want to be – daily calibration is ideal.


Pick the right electrode for your sample

Why – General purpose electrodes are functional for a wide variety of applications but not ideal for all samples.

Fix – Based on your sample you may require an electrode designed for food, high-low temp, non-aqueous, or other types of samples.


Open or loosen the fill hole cap

Why – A closed electrode fill hole may lead to slower stabilisation times.

Fix – Loosen or remove the fill hole cap. Remember to put it back when storing the electrode. (Not applicable for non-refillable electrodes).


Keep the electrolyte level full

Why – Electrolyte flows out from the reference junction over time. Low electrolyte levels may cause erratic readings. (not applicable for non-refillable electrodes).

Fix – Ensure that your electrode fill solution level is no less than one-half inch from the fill hole cap.






Properly submerge your electrode

Why – Both the pH sensing glass and reference junction need to be completely immersed in order to function properly.

Fix - Add enough sample to submerge both the junction and sensing glass.


Inspect your electrode

Why – Over time, the sensing portion of the glass becomes less responsive and will eventually fail. Damage from use is also possible. This will cause erroneous readings.

Fix – Check your electrode for damage and perform a slope and offset calculation.
