The Ultrameter II 6PFCE provides a comprehensive suite of in-situ water quality analysis tools that are designed to replace more costly and less convenient laboratory equipment. A true, one-handed instrument, the 6PFCE delivers Conductivity, Resistivity, TDS, pH, ORP, Free Chlorine Equivalent (FCE™), and Temperature measurements quickly and easily with the press of a button.

Unlike other similar meters, the 6PFCE Conductivity/TDS measurements feature the ability to select from one of three pre-programmed solution models, KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard, or to program a User solution mode based on a known solution yourself. The result is benchtop accuracy of plus or minus one percent of reading in a handheld instrument. Temperature compensation is automatic to 25°C or can be disabled by the user as required. Autoranging capabilities provide increased reading resolution across a broad range of applications.

pH readings are also temperature compensated, and you can choose to perform a 1-, 2-, or 3-point calibration depending on the range of samples measured to achieve plus or minus .01 pH accuracy. The pH sensor is of a proprietary construction and includes a large potassium chloride solution reservoir for long life. Myron L pH sensors are also user replaceable.

ORP measurements utilise a 99.9% pure platinum electrode and a reference junction that is shared with the pH sensor resulting in an accuracy of plus or minus one millivolt.

In addition, the 6PFCE features a groundbreaking new way to determine Free Available Chlorine based on a predictive ORP value. Empirical measurements of the chemical activity of a solution are made without the hassle and subjectivity of colorimetric and test-strip methods.

Calibration is simple to perform using up and down arrow keys and a digital interface. And the 6PFCE is IP67 dust-tight and waterproof, NEMA 6 submersible, and buoyant.
