The Myron L Ultrameter II is a prime example of how high-tech engineering can greatly simplify and streamline a task. Regardless of the function, simply fill the cup, push a parameter button, and take the reading — multi-parameter water measurement made effortless.

Two models are available: the 4PII measures conductivity, TDS, resistivity, pH, ORP, and temperature; the 6PFCE adds free chlorine measurement for applications that require it. Both feature autoranging, adjustable temperature compensation, 100-reading memory, and auto-off.
