£149.00 (exc. VAT) £178.80 (inc. VAT)

The HI-2111B 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.

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

  • The HI-2111B uses high temperature (HT) glass, spherical bulb, and glass body.

    HI-2111B Glass Bodied pH Half Cell Electrode information

    Hanna's extended description

    The HI-2111B is a pH half-cell for general purposes and strong alkaline solutions.

    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. Other types 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.

    BNC Connection – BNC is one of the most commonly used connector types in pH meters and electrodes. Compatible with any meter or electrode that uses BNC connectors.
