HI1053B pH Electrode with Sharp Tip BNC Port

Producer: HANNA Instruments

SKU: HANNA-HI1053B Category: Hanna experimental measuring equipment

– Glass body

– Refill electrolyte solution

– 3 ceramic junctions for faster measurement response

– Conical pH sensor head

– Ideal for emulsions, fats and creams, soils and semi-solid samples, clean water, and measuring samples at cold temperatures.

Hanna Instruments offers a line of pH electrodes designed for a variety of applications. The type of glass used for the pH sensor, bulb shape, body material, type of junction, type of reference, and electrolyte used are among the design considerations.

The HI1053B uses low temperature (LT) glass, conical bulb, glass body, single ceramic frit, triple ceramic junction and is refillable with 3.5M KCl.

Low Temperature Glass

A standard pH electrode using general purpose (GP) glass has a resistance of 100 megaohms at 25°C. The HI1053B uses LT (low temperature) glass which has a resistance of approximately 50 megaohms at 25°C. As the temperature of the glass decreases in the sample, the resistance of the LT glass will approach that of GP glass. If GP glass is used, the resistance will increase above the optimum range, increasing the impedance and ultimately affecting the measurement. The HI1053B is suitable for use with samples that measure from -5 to 100°C.

Conical electrode tip

The conical electrode tip allows penetration into solids, semi-solids, and emulsions for direct measurement of pH in food products, soils, and emulsions such as hand creams.

Glass body

The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and can be easily cleaned. The glass body also allows for rapid heat transfer to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The reference potential is stabilized more quickly than equilibrium.

Ceramic triple junction

The triple ceramic junction allows for a higher flow rate of electrolyte from the reference cell into the solution. A standard pH electrode will use a single junction allowing 15 to 20 µL/hour of electrolyte to flow; the HI1053B has three ceramic junctions, providing 40 to 50 µL/hour of electrolyte to flow. The high flow rate provides a faster electrode response and more stable measurements in viscous solutions or samples of low conductivity.

Dual reference junction

The double junction design has an internal chamber that contains the reference wire. Silver ions are present in the electrolyte of the internal chamber, which contains the Ag/AgCl reference wire; the electrolyte outside this chamber is silver free. The double junction design virtually eliminates the transfer of silver from the electrode to the sample. This design allows measurements in applications where silver ions are undesirable in samples or where sulfites are present that can cause silver to precipitate and clog the junction. Clogged junctions will result in drifty and unstable results.

Telectrolytic magnet

The HI1053B 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 silver as with the single junction electrode.

BNC connection

The HI1053B uses a BNC connector. This type of connection is universal and can be used on any pH meter that has a female BNC probe input. Other types of connections include DIN, screw type, T-type, and 3.5mm. Each meter typically has a unique connector and cannot be interchanged.
