Combines the versatile Testrr design with highly accurate, spear-tip electrode

 

Cole-Parmer Instrument Company introduces the pH Spear handheld meter, the latest addition to the Oakton Testr series. This meter features a redesigned, waterproof Testr housing with large, 1-1/16" tall display and three-segment battery life indicator. The unique junction design provides increased electrolyte flow resulting in greater contact between the sample and the reference junction for fast response. It also prevents silver chloride loss from temperature-induced variations, making for an extremely stable reference potential-producing measurements that are rapid, precise, and reliable.

The meter's IP67-rated housing floats if dropped in water, while the large display uses three simple buttons for easy input. Auto-buffer recognition of U.S. and NIST buffers provides for easy three-point pH calibration. Additional features include hold function, auto-off function, and self-diagnostic messages.
