Laboratory electrode HI11310

pH

The HI11310 is a combination, glass, refillable pH electrode with a built-in temperature sensor. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments edge® Tablet Meters. Stores its calibration data making it easy to change our smart electrodes or adjust for different samples. Built-in temperature sensor for temperature compensated measurements in a single probe. Great for general purpose laboratory use. Built-In Microchip The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used. This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot-swapping of probes without having to recalibrate. 

All pH measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analog measuring system. Electrical noise can be generated from a built-in temperature sensor and while working in a humid environment. Spherical Glass Tip The spherical shaped tip design allows for a wide area of contact with the sample. This permits a faster electrode response with a higher degree of stability. The HI11310 utilizes a high temperature (HT) glass formulation. 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 HI11310 is used at elevated temperatures the resistance decreases to approach the that of GP glass.
