PEI Body pH Half-Cell Electrode with BNC Connector


The HI2112B is a PEI body pH half-cell electrode with a BNC connector. This sensing electrode is made with general purpose glass and is to be used in conjunction with a reference half-cell electrode. This design consideration is ideal for general purpose measurements.

•  BNC Connection
•  Durable PEI Body
•  Half-Cell Design

  The HI2112B uses general purpose (GP) glass, spherical bulb, and PEI body.
General Purpose Glass Formulation
•  General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use.
•  A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring pH of samples that are at ambient temperatures.
•  The HI2112B is suitable to use with samples that measure from 0 to 70°C.

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

  PEI Body
•  The body of the HI2112B is composed of polyetherimide (PEI) resin.
•  The PEI body is suitable for a wide range of applications and excels in field measurements due to its durability.
•  The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode.
•  The PEI plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.

  BNC Connector
•  The HI2112B 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.
