OAKTON® Waterproof pH Testr® Meters

Waterproof pH Testr Meters Have Three-Point USA or NIST Push-Button Calibration with Buffer Recognition

Up to ±0.01 pH accuracy is displayed on a large, easy-to-read, dual-display LCD. Keypad clicks to confirm operation. Freeze and auto shut-off functions. Freeze function is useful when measuring in low light or confined spaces. Waterproof pH Testr Meters offer self-diagnostic messages, nonvolatile memory and automatic temperature compensation.
