Full Description Specification

This design is ideal for use in strong alkaline solutions as well as for general purpose measurements.

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

The HI-2111B uses high temperature (HT) glass, spherical bulb, and glass body. This electrode has a coaxial cable and BNC connector.

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 HI-2111B is used at elevated temperatures, the resistance decreases to approach that of GP glass. The HI-2111B 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 HI-2111B 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.
