Oakton pHTestr® Series 50 Waterproof Pocket pH Tester (WD-35634-15)

The Oakton pHTestr 50 has a replaceable double junction sensor for longer life, an expanded number of applications, and easy maintenance. Double-junction electrode sensor handles wastewater and solutions containing sulfides, heavy metals, and TRIS. Electrode sensor offers a clog-resistant Kynar® junction and a recessed, glass pH bulb to protect against breakage. Valox sensor housing resists most chemicals. The keypad clicks to confirm operation, and allows access to a variety of functions. Calibrate up to three pH points with the auto-buffer recognition at both USA and NIST standard buffers. Additional features include an automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator.
