Gel Filled PEI Body ORP Electrode with DIN Connector for Field Applications


The HI3620D is a PEI body, single junction ORP electrode with a built-in temperature sensor. This electrode has a single ceramic junction in the outer reference cell and the ORP sensing pin is made with platinum. The HI3620D connects to the meter with a DIN connector that is proprietary to the HI98140, HI98150, HI98230, and HI98240 meters. This electrode also features a rugged PEI (polyetherimide) body that has the chemical resistance of a glass body in an unbreakable plastic making it ideal for field and industrial applications.

•  DIN connector for use with the HI98140, HI98150, HI98230, and HI98240 meters
•  Gel Electrolyte
•  Platinum Sensing Pin

  The HI3620D features a platinum sensing pin, PEI body, and a single ceramic junction.
PEI Body
•  The body of the HI3620D 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.

  Single Ceramic Junction
•  The outer junction of an electrode, also known as a salt bridge, is necessary component of the electrical circuit.
•  The movement of ions must flow through the junction for a steady reading.
•  The outer reference has a single ceramic frit.  Other junction types are available with higher flow rates and made with different materials.

  DIN Connector
•  The HI3618D uses a DIN connector.
•  This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable.
•  Other type of connectors include BNC, screw type, T-type, and 3.5mm to name a few.
