FC230B

Description

The FC230B is a PVDF body, single junction pH electrode that has a BNC connector. The FC230B electrode 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, along with the optional stainless steel blades, is ideal for pH measurements in products such as meats and semi-frozen food products. The recommended operating temperature range is from 0 to 50°C.

•  Low Temperature Glass
•  Open Junction
•  Stainless Steel Piercing Blade (optional)

The FC230B 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 FC2323 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.

  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 FC230B

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

  Open Junction Reference
•  Suspended solids and proteins found in food products will clog a conventional ceramic reference junction. T
•  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.

BNC Connector
•  The FC230B uses a BNC connector.
•  This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input.
•  Other type of connectors include DIN, screw type, T-type, and 3.5mm to name a few.
•  These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
