Hanna Flat Tip pH Electrode for Skin and Surfaces with Screw Connector – HI1413S/50

The electrode features an open junction system filled with viscolene (hard gel) electrolyte that is free from silver chloride, significantly reducing the risk of clogging and contamination while maintaining stable and responsive performance over time. Its single reference junction with Ag/AgCl ensures consistent measurement accuracy in both controlled laboratory settings and field environments. The use of low temperature (LT) glass allows reliable operation across a temperature range of 0 to 50°C, making it suitable for both ambient and cooler sample conditions.

Designed for user convenience and durability, the HI1413S/50 includes a secure screw cap connector that ensures a stable connection to compatible pH meters, along with a 0.5 meter coaxial cable that provides flexibility during handling and testing. With a 12 mm outer diameter and a maximum pressure rating of 0.1 bar, the electrode is built for robust performance while remaining easy to clean and maintain.

Widely used in applications such as clinical diagnostics, cosmetic and skincare testing, material science, food and pharmaceutical research, and industrial quality control, this electrode offers a perfect balance of precision, durability, and ease of use. It is an essential tool for professionals who require accurate surface pH measurements in challenging testing environments. pH Electrodes
