HI2111B

Description

The HI2111B is a glass body pH half-cell electrode with a BNC connector. This sensing electrode is made with high temperature glass and is to be used in conjunction with a reference half-cell electrode. This design consideration is ideal for use in strong alkaline solutions as well as for general purpose measurements.

•  BNC Connection
•  Half-Cell Design
•  High Temperature (HT) Glass

  The HI2111B uses high temperature (HT) glass, spherical bulb, and glass body.
High Temperature Glass Formulation
•  The measurement of pH at very high temperatures is detrimental to the sensitive glass bulb and will shorten the life of it.
•  A pH electrode with general purpose (GP) glass will have a resistance of 100 megaohms at 25°C while the resistance of HT glass is around 400 megaohms at 25°C.
•  As the HI2111B is used at elevated temperatures the resistance decreases to approach the that of GP glass.
•  The HI2111B is suitable to use with samples that measure from 0 to 100°C.

  Spherical Bulb
•  The spherical bulb is for general purpose use.
•  Other tip shapes include conic for penetration and flat tip for surface measurements.

  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 allows for a fast transfer of heat to the internal reference electrolyte.
•  The mV generated by the reference cell is temperature dependent.
•  The faster the electrode reaches equilibrium, the steadier the reference potential.

  BNC Connector
•  The HI2111B 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.
