Guaranteed performance  Epsilon 1 is pre-calibrated in the factory for analysis of phosphorus, sulfur, calcium and zinc in unused lubricating oil in compliance with the latest ASTM D6481 test methods.    Maximum sensitivity  The thin window Ag anode X-ray tube, designed and manufactured by PANalytical, ensures high quality and sensitivity. The selection of Ag as anode material is ideal for the accurate quantification of phosphorus and sulfur without interference of possible line overlaps in the XRF spectrum, leading to more reliable results. The 50 kV X-ray tube and generator is ideal for exciting higher-energy elements like zinc, resulting in faster analysis times.    Self-contained system  A built-in computer running Microsoft Windows 7 with powerful CPU and 120 GB hard drive ensures flexibility to store and handle thousands of results. The high-resolution, 10.4” LCD touch screen is ideal for easy walk-up operation.    Easy communication  USB and network connections for use of standard computer peripherals for extended use, application development and seated operator.    Spillage protection  In order to shield the delicate heart of the system from spillage, a protection foil is in place. In case of spillage, the foil can be replaced easily by the operator.
