The FC210B is a glass body, double junction pH electrode that has a BNC connector. The FC210B 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 cream, yogurt, or other semi-solid or emulsified samples. The recommended operating temperature range is from 0 to 50 C.
Features:
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 FC210B 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.
Glass Body
The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allow for a fast
transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium
the steadier the reference potential.
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.
BNC Connector
The FC210B 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.
