Hanna Spare Checker pH Electrode - HI1271

The HI1271 Spare Checker pH Electrode is a high-quality replacement probe compatible with HI98100, HI98103, and HI98115 Checker pH meters. Featuring a slim 8 mm polypropylene body, this electrode is engineered for insertion into test tubes and other small laboratory vessels where space is limited.

This single junction electrode employs an open junction and viscolene electrolyte, optimizing it for stable, reliable, and accurate pH readings across a broad measurement range of pH 0 to 13. The spheric tip (diameter: 3 mm) enables precise measurement, while the screw cap design allows for quick, tool-free replacement in compatible meters. With a durable polypropylene construction, the HI1271 electrode maintains chemical resistance and long service life in laboratory environments.
