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.
Polyvinylidene fluoride (PVDF) is a food grade plastic that is resistant to most chemicals and solvents, including sodium hypochlorite. PVDF has abrasion resistance, mechanical strength, and is resistance fungal growth as well as ultraviolet and nuclear radiation.
Open Junction Reference
The open junction design uses 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 the junction impermeable to clogging, for fast responses and stable readings.
Screw Cap Connector
The FC200S uses a screw cap connector to attach directly to the meter and can be interchangeable with other meters by using a Hanna BNC extension cables.
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 FC200S is suitable to use with samples that measure from 0 to 50℃.
