Oakton pH Testr® 50S Spear-Tip Waterproof Pocket Tester, Premium 50 Series

With its unique junction design provides increased electrolyte flow, resulting in greater contact between sample and reference, ensuring fast, stable readings. The electrode junction is 200 times larger than standard electrodes, making it virtually impossible to clog. Rugged tip makes it ideal for soft solids and semi-solid materials like meats, cheeses, and fruit. The long, thin electrode can be used to determine pH in test tubes, micro tubes and other narrow containers. Additional features include a hold function, auto-off function, self-diagnostic error messages, and a three segment battery life indicator.
