pH Electrode with Clogging Prevention System (CPS™) and BNC Connector - HI1048B

HA-HI1048B

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna’s Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode.

The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.

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 HI1048B is suitable to use with samples that measure from 0 to 80°C.

 

Spherical Glass Tip

The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.

CPS Sleeve Junction

Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.

 

Double Junction Reference

A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contains sulfides that can cause the silver to precipitates and clog the junction. Clogging of the junction will result in drifty and erratic readings.

 

Refillable

The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.

 

Glass Electrode 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 HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a 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.
