Ultraviolet fluorescence sulfur analyzer

summary:

SH / T 0689, ASTM d5453 light hydrocarbon and engine fuel and other oil determination of total sulfur content (UV fluorescence method). The instrument can be widely used in petroleum, chemical industry, electric power, coal, food, environmental protection and other fields.

Technical parameters:

L sample type: liquid, solid and gas (with corresponding injector)
USB port is used for data acquisition and transmission. The data acquisition card is imported, and the detection limit is 1uv.
