pH electrode, WTW SenTix® Sp: Electrode with glass shaft, flat tip, and S7 plug head. For measurements on surfaces with minimal liquid down to single drops, or on paper, film material, gel culture media, and more. With polymer electrolyte without refilling. Shipped without cable.

Measurements in solid or viscous samples is challenging and requires electrodes which are robust, ensure correct flow of electrolyte, and that are easy to clean. Sensors with these traits are often used for applications in the industries of food, beverage, and cosmetics.

The electrodes in the SenTix® series from WTW are designed to cover the common measurements in pH and mV. The electrodes area available in glass or plastic, for general or specialised purposes, and with a range of junctions/diaphragms, which makes it possible to measure in aqueous solutions, protein-rich samples, solids and viscous samples, on surfaces, and much more. The series is available with and without various cables and temperature sensors, to make it easy to find the correct sensor for your pH meter. Collectively, they represent high quality, low pricing, robustness, and easy use.
