HI5312

Description

The HI5312 is a glass body, refillable, double junction, half-cell reference electrode with a 4 mm banana connector. This electrode has a PTFE sleeve junction in the outer reference cell and is made for use in temperatures ranging from -5 to 80°C. This design consideration is made for measurements in samples with suspended solids, and can also be used in a variety of titrations.

•  Half-Cell Design
•  Refillable Electrode
•  PTFE Sleeve Junction

  The HI5312 uses a glass body, PTFE sleeve junction and is refillable with 3.5M KCl.
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 equilibrium the steadier the reference potential.

  PTFE Sleeve Junction
•  Conventional pH electrodes use ceramic junctions that clog quickly when used in samples with high amounts of particulates.
•  When the junction is clogged, the electrode does not function.
•  The use of a polytetrafluoroethylene (PTFE) sleeve junction prevents clogging of the junction and allows proper flow of the liquid electrolyte.
•  As a result, pH electrodes with sleeve junctions stay fresh up to 20 times longer than conventional electrodes.

  Refillable
•  The HI5312 is a refillable reference electrode.
•  Since it is a double junction electrode the fill solution is the HI7082 3.5M KCl.
•  This solution does not contain any silver as with single junction electrode.
•  The absence of silver will prevent any silver precipitate from forming at the junction surface and clogging it. Clogging of the junction will result in drifty and erratic readings.

  4 mm Connector
•  The HI5312 uses a 4 mm banana connector.
•  This type of connector is easily plugged into the reference input on suitable meters.
•  Other type of connectors include BNC, 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.
