HI1048P Clogging Prevention Digital pH Electrode (CPS™)

Producer: HANNA Instruments

SKU: HANNA-HI1048P Category: Hanna experimental measuring equipment

The HI1048P is a glass body, refillable, pH electrode with a BNC connector and pin. The pin connector is used to enable the CAL Check function of the HI2221, HI2222, and HI2223 benchtop meters.

This electrode features a dual reference junction, Hanna’s Clogging Prevention Technology (CPS™) and a spherical glass sensing bulb made of regular glass. The pH electrode is ideal for wine and juices due to their high solids content which would clog a regular pH electrode.

Clogging Protection System (CPS™) Technology

Electrolytic refillable electrode

Double joint design

Spherical glass head

The spherical sensing tip design allows for a larger surface area in contact with the sample resulting in a faster response with greater stability. The HI1048P uses low temperature (LT) glass. A pH electrode has a resistance of 50 megaohms at 25°C. As the temperature of the glass decreases in the sample, the resistance of the LT glass approaches glassGP. If used glass GP, the resistance will increase to the maximum, leading to increased impedance and eventually affecting the measurement. The HI10480 is suitable for use with samples that measure between 0 and 80°C.

CPS Anti-Clog Button

CPS™ (Clogging Prevention System) is an innovation in electrode technology. Conventional pH electrodes use ceramic junctions that clog quickly when used in wine. When the junction becomes clogged, the electrode will not function. CPS™ technology uses the porosity of the ground glass combined with a PTFE sleeve to prevent junction clogging. The ground glass allows for proper liquid flow, while the PTFE sleeve prevents dirt from getting in. As a result, pH electrodes with CPS™ can be refreshed up to 20 times longer than conventional electrodes.

Glass body

The glass body of the electrode is suitable for many applications due to its chemical resistance. The glass electrode is compatible with many non-aqueous solvents and other aggressive chemicals. The glass is also resistant to many forms of radiation, such as ultraviolet radiation.

Double reference joint

A double electrode junction has an internal reservoir that surrounds the reference wires. Silver ions are contained in the electrolyte of the internal reservoir, which holds the Ag/AgCl reference wire; the electrolyte outside the chamber is silver-free. The double junction design prevents silver from passing from the electrode to the sample. This design allows measurements in applications where silver ions are not desired in the sample or where silver precipitation on the junction is prevented.

BNC + battery connector
The HI1048P has a BNC and pin connector. The BNC connector is universal in that it can be used on any pH meter that has a female BNC probe input. The pin connector is used for the CAL Check function on the following benchtop pH meters: HI122, HI123, HI221, HI223, HI223, HI2221, HI2222, and HI2223.
