In-Situ Water Quality Analysis

Myron L^® Company’s 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 preprogrammed solution models, KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard, or users can program a custom solution mode based on a known solution themselves. The result is benchtop accuracy of ±1% of reading in a handheld instrument. Accuracy increases to ±.1% of reading at calibration point. 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.

The 6PFCE also 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. WW

The Myron L^® Company is a manufacturer of high quality and simple-to-operate conductivity and pH instrumentation for municipal, commercial, and industrial water quality control, chemical concentration testing, and process control. Learn more at www.myronl.com.
