ASTM D762 Automatic Hydrogen Sulfide in Fuel Oils Tester   

Model: JF7621

Product Introduction: 

The instrument is designed and manufactured in accordance with the requirements of the ASTM IP test standard. A small amount of sample is diluted with a diluent and heated to 60°C in a metal bath under precise temperature control to release the H2S in the sample. Use a clean Air is used as the carrier gas, 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 flow meter. When the H2S in the sample is completely released, the instrument will automatically calculate H2S. Cumulative concentration.
