Description
Cole-Parmer® Oakton® pHTestr® 50S Spear-Tip Premium 50 Series Waterproof pH Pocket Tester, WD-35634-25
Features:
- Redesigned leakproof cap functions as a sample/calibration cup, hydrating cup, and stabilizing base to stand the meter upright
- Rugged spear tip is ideal for soft solids and semisolid materials plus for determining pH in test tubes, micro tubes, and other narrow mouth containers
- Replaceable sensor module with double-junction platinum electrode [See 91-2611-64 (WD-35634-27)] for money savings
- Unique junction of the spear tip sensor provides increased electrolyte flow resulting in greaster contact between sample and reference for fast, stable readings
- Junction is 200 times larger than standard electrodes, making it nearly impossible to clog
- Simple operation with MENU button, 1-button calibration
- Valux® body resists most chemicals and is rugged, dustproof, waterproof, and IP67 rated
- Auto-shutoff
- Up to 3-point calibration with auto-buffer recognition of both USA and NIST standard buffers
- Automatic temperature compensation
- Low-battery indicator and self-diagnotic messages
- HOLD and √ (reading stabilization) functions
