Section II: Key Features

The Ultraviolet Fluorescence Sulfur Content Analyzer is a new generation of precision laboratory instrument developed by combining the principles of ultraviolet fluorescence with computer technology. The instrument boasts outstanding features such as high sensitivity, low noise, wide linear range, strong anti-interference ability, high analysis accuracy, easy operation, and stable and reliable results. The instrument's cooling fan automatically turns on and off, eliminating the hassle of waiting for the fan to turn off after the sample is processed. It is widely applicable in the fields of petroleum, chemicals, electricity, coal, food, environmental protection, and others, and is currently the most advanced sulfur content analyzer both domestically and internationally. The product complies with standards such as ASTM D5453 and SH/T 0689.

The instrument is mainly composed of the main unit, temperature gas flow control unit, reaction chamber, sampler, computer, printer, and other components.

● The instrument uses the most popular international USB port communication, standard 24-bit data acquisition, with the minimum detectable signal less than 1 microvolt.

● The main components of the instrument are original imported parts, with the overall performance surpassing similar domestic instruments and capable of replacing imported products.

● Photomultiplier Tube (PMT) high voltage is adjustable at will, calibration curves can be corrected using single-point or multi-point calibration, easy to operate.

● Data can be stored, accessed, printed freely, and relevant issues encountered can be resolved based on on-site data files.

●The instrument boasts exceptional sensitivity, linearity, and anti-interference capability, ensuring precise and reliable analysis results.

● The software can run on all current operating systems, with strong adaptability. The instrument software is powerful.

● Instrument connection operations, including the use of quartz tubes and UV lamps, please refer to the instruction manual.
