Automatic Hydrogen Sulfide in Fuel Oils Tester ASTM D7621
Model: JF7621
The instrument is designed and manufactured in full accordance with the requirements in the ASTM IP test standard. The trace sample is diluted with diluent and heated to 60°C in a temperature-controlled metal bath to release the H2S in the sample. Clean air is used as the carrier gas. The H2S is carried into the measuring cell of the electrochemical sensor, and the instantaneous concentration of H2S is measured. The air flow is measured and controlled by a digital mass flowmeter. When the H2S in the sample is completely released, the instrument will automatically calculate the cumulative concentration of H2S.
