HANNA HI1207 Replacement pH Electrode for use with HI98103 Checker® pH Tester, Body: Plastic, Electrolyte: Gel, Connection: Screw Top

Accurate and reproducible pH measurements depend on proper attention to calibration. When it is necessary for the user to measure pH values outside the standard buffers range. The HI 120 benchtop pH meter can offer help in these situations. Equipped with automatic calibration of up to 5 points, these meters allow the user to tailor the calibration window to the appropriate range. Select from among the 7 factory stored values and up to 2 customized values, for specific applications. With Hanna's featured Calibration Check™, calibration information and probe condition are readily observed directly on the display screen, with a %-value indicating the electrode condition and response consistencies. These meters record and store significant data capture including time, date links to readouts and are compliant with GLP.
