The pH electrode InLab® Surface from Mettler-Toledo has a flat tip and is designed for measurements on surfaces with minimal liquid, such as sinle drops. The electrode has a robus shaft in polysulfone for extra protection in harsh environments. 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.
