pH Electrode PEI Body 3.5mm Port HI12300

Producer: HANNA Instruments

SKU: HANNA-HI12300 Category: Hanna experimental measuring equipment

pH Electrode PEI Plastic Body 3.5mm Port

The HI12300 is a plastic body, double junction pH electrode with a built-in temperature sensor. The electrode connects to the meter using a 3.5mm port dedicated to digital electrodes.

The electrode incorporates a microchip that stores sensor type, serial number, and calibration information. The HI12300 has a single ceramic junction and the spherical pH sensing portion is made of glass. The electrode has a rugged PEI (polyetherimide) body that is chemically resistant and shatterproof making it ideal for field and industrial applications.

Microchip integration

The integrated microchip stores sensor type, serial number and calibration information including date, time, slope, offset, probe condition and buffers used. This information is automatically retrieved by the digital meter when the electrode is plugged in. The ability to transfer information allows for quick exchange of probes without the need for recalibration. All pH measurements are made in the electrode and transferred digitally to the meter. This helps to avoid noise associated with traditional high impedance analog measurement systems. Electrical noise can be generated from the built-in temperature sensor and when working in humid environments.

Spherical glass head

The spherical sensor tip design provides a larger contact area with the sample resulting in a faster response with greater stability. The glass sensor tip has an impedance of 100 megaohms. This means that the measurement conditions are optimal at ambient temperature. Using high or low temperature glass around ambient temperature would be suboptimal due to long response times or shortened electrode life.

PEI plastic body

The body of the HI12300 is constructed of polyetherimide (PEI) plastic. The PEI body is suitable for a wide range of applications and is highly durable. The guard around the spherical glass tip reduces the possibility of breakage due to impact or dropping. PEI is a high quality plastic that is resistant to many harsh chemicals.

Double reference joint

A double electrode junction has an internal chamber that surrounds the reference wires. Silver ions are contained in the electrolyte of the internal chamber, 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.

Integrated temperature sensor

The HI12300 incorporates a temperature sensor in the tip of the pH electrode. A temperature sensor provides a highly accurate temperature reading and should be placed as close to the pH electrode as possible to compensate for temperature changes across the membrane.
