Product information "FC2053 FoodCare pH Electrdoe with replaceble gel bridge electrolyte"

There are many chanllenges in measuring the pH of food products.  This is especially true for food products that have a high solids content that can clog the outer junction of the reference cell.  Every glass pH electrode has a reference electrdoe as part of the measuring circuit.  The reference cell has a junction, also know as a Salt Bridge, that isolates the inside portion of the cell from the sample being measured.  This junction must be free flowing in order to provide continuity with the sample.

Standard pH electrodes will use a porous ceramic frit for a junction.  When the junction becomes clogged with solids the continuity with the sample is disrupted and results in sluggish and erratic readings.  To overcome this, many of the Hanna Foodcare pH electrdoes use an open junction design in which there is no ceramic barrier but instead an exposed gel known as Viscolene.  This open junction design is clogging resistant  but it is still possible to force solids into the refeence as force is exerted on the probe to penetrate solid/semisolid samples.

The FC2053 is a technical advancement of the open junction design.  The FC2053 has a unique removable sleeve that is used as part of the open junction design.  When the readings become sluggish or erratic the sleeve is simply removed and both the sleeve and glass are cleaned.  After cleaning a few drops of the HI9071 electrolyte filling gel are added and the sleeve placed back into the probe.  Having a clean probe with a fresh reference electrolyte will improve the performance allowing for an extended life and reduced costs associated with frequest replacements.

Details

 

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.

For use with the HI98 Series of pH Meters, the FC2053 is an amplified pH electrode with a built-in temperature sensor. This probe is designed with low temperature (LT) glass, conical bulb, food grade PVDF body, and open junction with viscolene gel electrolyte.

Unique Open Junction with Removable Sleeve

The FC2053 has a unique removable sleeve that is used as part of the open junction design. When the readings become sluggish or erratic the sleeve is simply removed and both the sleeve and glass are cleaned. After cleaning, a few drops of the HI9071 electrolyte filling gel are added and the sleeve is placed back onto the probe. Having a clean probe with a fresh reference electrolyte will improve performance allowing for an extended life and reduced costs associated with frequent replacements. 

low temperature glass

Conical Glass Tip

The conical shaped tip design allows for penetration into solids, semi solids, and emulsions for the direct measurement of pH in a variety of food products including meat, cheese, yogurt, and milk.

Low Temperature Glass Formulation

The glass tip uses a special low temperature (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.

 pvdf body

PVDF Body

Polyvinylidene fluoride (PVDF) is a food grade plastic that is resistant to most chemicals and solvents used for disinfection in the food sector, including chlorine (bleach).

Quick Connect DIN Connector

The FC2053 uses a Quick Connect DIN connector that makes attaching and removing the probe simple, creating a watertight connection without twisting.

Cleaning:

The first step in cleaning the probe and replacing the gel electrolyte is to remove the PVDF sleeve from the probe.  With the probe sensing glass facing up, hold the sleeve with one hand and main body with the other. Gently twist and pull up to remove.

*Note: It is important to pull straight up along the axis of the electrode so as not to bend and damage the glass sensor.

 Next rinse the probe and sleeve in DI water. Remove any solids that might be present.

 *Note: Never wipe the green glass-sensing portion of the probe with a cloth or other tissue. Doing so can build a static charge and damage the probe.

For a thorough cleaning place the probe in cleaning solution for 15 minutes. Hanna offers a wide range of cleaning solutions including ones specific for meats, cheeses, and yogurts.

After 15 minutes the probe can be rinsed with DI water to remove the cleaning solution from the sensor.With probe sensing surface facing up the next step is to fill the compartment in the probe body with the supplied HI9071 bridge electrolyte. 

To put the sleeve back on simply insert back on the probe and make sure the black O-ring is seated into the probe body.  Extra electrolyte will be displaced through the open junction when the sleeve is placed back on

 

With the probe reassembled the excess electrolyte can be rinsed off with DI water.  If cleaning solution was used the probe should be placed in storage solution for 1 hour to ensure the glass is properly hydrated and the junction potential stabilized.  After replacing the gel electrolyte it is necessary to calibrate the probe wit fresh buffers before taking any measurements.

MAINTENANCE:

One final note, when the probe is not being used it is important to store properly.  A few drops of the supplied HI70300 storage solution is placed in the storage cap and the cap placed on the probe. This will keep the glass hydrated and prevent the gel from drying out.  

 

FEATURES | BENEFITS - FC2053 pH/Temperature Probe for Food Products Testing

Removable sleeve for cleaning of outer reference -  A common problem when testing food products is the clogging of the reference junction.  When this happens the electrical circuit from the indicating probe to the refence cell is disrupted resulting resulting in sluggish and erratic readings.  The FC2053 allows for cleaning of the the outer reference area of any solids/semi-solids that get trapped during measurement.

Replaceable gel electrolyte -  The FC2053 is supplied with the HI9071 electrolyte get to replace the get that is removed as part of the disassembly and cleaning process.

PVDF Body -  The PVDF body is a food grade plastic that offers durability.  PVDF plastic is resistant to the chlorine (bleach) that is a common chemical used for disinfection.

Conical Glass Tip - The conical shaped tip design allows for penetration into solids, semi-solids, and emulsions for the direct measurement of pH in a variety of food products.

Low Temperature Glass -  The FC2053 pH electrdoe used Low Temperature (LT), glass forthe sensing bulb.  The LT glass is a special glass formulation with a lower resistance when compared to general purpose (GP) glass.  This design is beneficial as many food products are stored at lower temperatures.  

Built-in Temperature Sensor - The FC2053 pH electrode features a built-in thermistor temperature sensor that is in the tip of the indicating pH electrode.  A thermistor temperature sensor provides for a high accuracy temperature reading.  The temperature reading is necessary in order to compensate for temperature variations that affect the electrode response.  The thermistor temperature sensor is located in the tip of the pH bulb for a fast and accurate temperature measurement that impacts a membrane potential as according to the Nernst equation.

Built-in Amplifier -  The FC2053 is an amplified pH electrode.  A pH measurement is a very sensitive measurement.  Humidity and electrical noise (i.e. pumps, motors and ballasts) will affect the measurement. By incorporating an amplifier into the probe the transmission of the pH measurement from the probe to the meter is unaffected.

Quick connect DIN connector -  Allows for a secure whaterproof connection between the pH and temperature probes and meter using a single cable.
