SLFA-60 X-ray Fluorescence Sulfur-in-Oil Analyzer

Description

Safer, Simpler and Swift: Effortless Sulfur Analysis in Oil
Ultra-low Detection Limit: It measures sulfur concentrations of 20 ppm or less, and can measure higher sulfur concentrations of crude and shale oil markets, up to 9.9999 wt%.
Portability at Its Best: Take it anywhere with ease – only 9 kg weight with small footprint.
Enhanced Safety: In addition to the thorough X-ray leakage test performed at the factory, the key switch and shield shutter provide additional protection for the operator.
Simple Operation: After selecting the calibration curves and measurement conditions, or selecting the correct calibration curve using the “A” mode, simply press the “MEAS” button to start the measurement.

The SLFA-60 is a compact sulfur-in-oil analyzer based on energy-dispersive X-ray fluorescence (EDXRF) technology. It is portable and can be used on-board, thanks to its pump-free and LN2-free optics. The SLFA-60 series does not require a laptop or external printer, making it flexible to install in any location.
The SLFA-60 has an integrated large-screen display and touch buttons on the main unit, which makes it easier for users to operate the device intuitively. The buttons are covered with a resin sheet to prevent oil from adhering to the device and make it easier to keep it clean. The SLFA-60 also has an integrated printer that can print out all the necessary information on 80 mm wide paper
The SLFA-60 has a protective membrane under the sample cell. It protects the optics (detector and X-ray tube) from accidental sample leakage. The protective membrane is a single unit that is easy for the user to replace.
