More About this Item
Our most advanced line of pocket testers, the Oakton 50 Series provides single and multimeter options for measuring pH, Conductivity, TDS, Salinity, and ORP. Replaceable double junction sensors provide durability and longevity against highly caustic, volatile or hazardous samples in both lab and field applications. Waterproof and designed to float in water, they are ideal for field-based testing environments – with a convenient loop for security line attachment.
50 series pocket meters include a replaceable double-junction electrode sensor that is designed for more aggressive applications, including wastewater and solutions containing sulfides, heavy metals, and TRIS. The electrode sensor offers a clog-resistant Kynar® junction and a recessed, glass pH bulb to protect against breakage and allow for easy maintenance and replacement. A Valox sensor housing resists most chemicals.
An easy-to-use four-button keypad allows for technician level use and measurement with quick access to a variety of functions. Up to 3 calibration points with 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.
