Technical Specification for KN-4294 Energy-Dispersive X-ray Fluorescence (ED-XRF) Sulfur Analyzer. Base Configuration: Benchtop analytical instrumentation utilizing the energy-dispersive X-ray fluorescence principle for rapid, non-destructive and highly precise quantitative determination of total sulfur content in gasoline, diesel, crude, and heavy residual oils. Architectural Design: Mechanical, electrical, and microprocessor integrated platform featuring automated data processing, digital calibration matrixes, and an integrated WH-AA thermal sensitivity printing unit (57mm wide roll layout). Practical Operations: Rapid sample cycle determination times, straightforward calibration routines against reference oil baselines, and built-in diagnostic test routines. Maintenance Requirements: Periodic regular cleaning of the heat-sensitive printer head and intake roller assembly using a soft cotton swab saturated with high-purity laboratory alcohol to ensure printing life span and block operational dust artifacts. Power Supply: AC 220V +/-10%, 50Hz.
