Hanna Flat Tip pH Electrode for Skin and Surfaces with BNC Connector - HI1413B

The HI1413B Flat Tip pH Electrode is engineered for direct measurement of pH on planar and irregular surfaces such as skin, leather, paper, and emulsions. This glass body electrode utilizes a unique open junction that employs a viscolene gel electrolyte resistant to clogging, ideal for measurement scenarios that could obstruct standard junctions. The flat tip design ensures even contact and accuracy across measured surfaces.

With a measuring range of pH 0 to 12 and an operating temperature from 0 to 50°C, the HI1413B supports a diverse range of laboratory, environmental, industrial, and process applications. It features a single, Ag/AgCl reference cell, a 1-meter coaxial cable, overall length of 153.5 mm (110 mm body), and a robust BNC connector, making it compatible with most pH meters.

• Reliable, clog-resistant open junction for stable long-term measurements.
• Flat tip design is particularly well-suited for surface and non-liquid samples.
• Glass body construction for optimal chemical resistance and durability.
• Single reference, Ag/AgCl cell delivers stable readings over time.
• Viscolene gel electrolyte without AgCl prevents contamination of sensitive samples.
• Coverage of the 0–12 pH range is compatible with most analytical needs.
• Max. pressure: 0.1 bar supports use in various field conditions.
• Coaxial cable (1 m) and BNC connector ensure ease of use with common laboratory instruments.
• Typical applications: direct skin pH testing, quality control of leather and paper industries, surface & process analytics.

Industrial/laboratory use: R&D, analytical, process validation, quality assurance, cosmetic studies, and environmental fieldwork.
