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. Simply rinse and fill the sensor well and/or cell cup with solution, press a measurement key, and note the measurement value or store it in memory. With the optional bluDock™ accessory package the 6PFCE can transmit data wirelessly to the free Myron L Guardian2 desktop application. This application saves data in .mlcx files in a secure, encrypted format. For users who wish to view and/or manipulate data in other applications, Guardian2 can export data files in .csv, .xls, .xlsx and .pdf formats.
Unlike other similar meters, 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. The result is benchtop accuracy of ±1% of reading in a handheld instrument. Temperature compensation for the three preprogrammed solution types is automatic to 25°C or can be disabled by the user as required. When working with a known solution, the user can program a temperature compensation ratio and a Conductivity to TDS conversion ratio in User mode. Autoranging capabilities provide increased reading resolution across a broad range of applications.
pH readings are also temperature compensated. The user can choose to perform a 1-, 2-, or 3-point calibration depending on the range of samples measured to achieve ±.01 pH accuracy. The pH sensor is of a proprietary construction and includes a large potassium chloride reference solution reservoir for long life. Myron L pH sensors are also user-replaceable.
ORP measurements utilize a 99.9% pure platinum electrode and a reference junction that is shared with the pH sensor. Accuracy achieved is ±1 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. Myron L service and technical support are included for the life of the product.
