FC400B

Description

The FC400B is a PVDF body, double junction pH electrode that has a BNC connector. The FC400B 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 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
•  PVDF Body

The FC400B uses low temperature (LT) glass, conical bulb, 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 megohms compared to general purpose (GP) with a resistance of about 100 megohms.
•  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 FC400B 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.

  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 Double Junction Reference
•  FC400B has an open double junction reference design. pH electrodes are available as single junction or double junction.
•  The junction also known as a salt bridge is necessary component of the electrical circuit.
•  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.

  BNC Connector
•  The FC400B 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.
