HI3133B

Description

The HI3133B is a glass body ORP half-cell electrode with a BNC connector. This sensing electrode is made with a platinum pin and is to be used in conjunction with a reference half-cell electrode. This design consideration is ideal for use in ORP titrations as well as for general purpose measurements.

  The HI3133B uses a platinum pin and glass body.
  Platinum Sensing Pin
•  The HI3133B ORP sensor is made with platinum.
•  An ORP sensor must be chemically inert; it cannot be oxidized or reduced itself.
•  It must also have the proper surface characteristics to promote rapid electron  exchange, a property known as high exchange current density.
•  Two noble metals have proven to work well for this purpose: pure platinum and pure gold are both used in the construction of ORP sensors.
•  The platinum sensor is often preferred because it is mechanically simpler and safer to produce. Platinum can be welded to glass and has the same thermal coefficient.
•  The platinum sensor signal is carried through the electrode body, and together with the reference signal is conducted to the measurement meter.

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

  BNC Connector
•  The HI3133B 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.
