Reference Electrode for Samples with Suspended Solids - HI5312

$348.62


Prices include GST. Not all items are in stock. Call 03 9769 0666 to confirm.

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℃.

This design consideration is made for measurements in samples with suspended solids, and can also be used in a variety of titrations.

Description

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.

The HI5312 uses a glass body, PTFE sleeve junction and is refillable with 3.5M KCl.

glass electrode body

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.

 

sleeve junction

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

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.

 

Banana pin connector

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.
