Waterproof pH Spear

Versatile, Convenient and Accurate Spear-tip pH Tester

  • Electrode junction is 200 times larger than standard electrodes, making it virtually impossible to clog
  • Rugged spear tip makes it ideal for soft solids and semisolid materials like meats, cheeses and fruit
  • Long, thin electrode can be used to determine pH in test tubes and other narrow containers

    The unique junction design provides increased electrolyte flow, resulting in greater contact between sample and reference, ensuring fast, stable readings. The double-junction design offers enhanced performance. Additonal features include a hold function, auto-off function, self-diagnostic error messages and a three-segment battery-life indicator.
