Waterproof pHTestr 30 is great for outdoor applications such as taking pH measurements in lakes and streams. Designed to float in water, you can even attach a line to the housing for easy retrieval. Valox sensor housing resists most chemicals.

The pHTestr 30 has a replaceable sensor for 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.

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 a automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator.

Meter includes: protective plastic storage case, lanyard, and batteries.
