Electrodes & Replacement Electrodes

The 4HA11310 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.

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.

Ideal for general laboratory use, the 4HA1131B is a glass-bodied combination pH electrode with a BNC connector for a quick and easy connection to any BNC pH meter. With a double junction design and the ability to change out contaminated electrolyte, this economical pH electrode ensures great results.

Gel Filled PEI Body pH Electrode with BNC Connector (4HA6XXX meters) The 4HA1230B pH electrode has a PEI body, double junction, and a BNC connector. The spherical pH sensing portion is made with general purpose glass, suitable for most pH measurements, and is protected by an extension of the durable PEI body.

The 4HA9813-61 and 4HA9810-61 are supplied with the 4HA1285-61 pH/EC/TDS/temperature probe with CAL Check^.™ The pH, EC, TDS, and temperature sensor are housed in a single body that connects to the meter with a DIN connector.

Hanna Instruments offers a wide variety of electrodes that are designed for many different applications. The sensing material, body material, and connection type used are just some of the design considerations. 4HA1285-6

The 4HA1271 is the Spare pH Electrode for 4HA98100 / 4HA98103 Checker^® pH meters. Replacing the pH electrode is both quick and easy. Simply unscrew the old probe to be replaced and screw on the new one. The 4HA1271 is a single junction pH electrode that has a slim 8 mm polypropylene body that easily fits into test tube and other small sized vessels.
