Backorder Now, once ordered your item will dispatch before the 21st of May 2025, call 1300 737 871 (NZ 0800 737 871 to confirm).
The HI1043P is a glass body, refillable, double junction pH electrode with a BNC and pin connector. The pin connector is used to enable the CAL Check function of the HI2221, HI2222, and HI2223 benchtop meters.
- Has a single ceramic junction in the outer reference cell and the pH sensing portion is made with high temperature glass.
- Designed specifically for hydrocarbons, paints, solvents, high conductivity samples, strong acids, bases, and for applications that require measuring samples in high temperatures.
- Its a refillable probe using HI7082 3.5M KCl.

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.
The measurement of pH at very high temperatures is detrimental to the sensitive glass bulb and will shorten the life of it. A pH electrode with general purpose (GP) glass will have a resistance of 100 megaohms at 25 C while the resistance of HT glass is around 400 megaohms at 25 C. As the HI1043P is used at elevated temperatures the resistance decreases and approaches the resistance of GP glass. The HI1043P is suitable to use with samples that measure from 0 to 100 C.
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.
The HI1043P is a double junction design. The junction 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. The ceramic is a porous material that is easily fused with the glass body and has a similar expansion coefficient. A single ceramic junction has a flow rate of 15-20 L/hour. Other junction types are available with higher flow rates and made with different materials.
The HI1043P has a BNC and pin connector. The BNC connector is universal in that it can be used on any pH meter that has the female BNC probe input. The pin connector is used to enable the CAL Check function on the following benchtop pH meters; HI122, HI123, HI221, HI222, HI223, HI2221, HI2222, and HI2223.
