GD-R3027 Automated Hydrogen Sulfide Analyzer


The Automated Hydrogen Sulfide Analyzer is designed and manufactured in full accordance with the requirements of relevant ASTM and IP test standards. A small amount of sample is diluted with diluent, heated to 60°C in a metal bath under precise temperature control, and the H2S in the sample is released. Clean air As a carrier gas, H2S is carried to the measuring cell of the electrochemical sensor, and the instant 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.

Functional Features:

1.Computer control, automatic measurement, automatic calculation results.

2.The air flow is measured and controlled by digital mass flowmeter.

3.The Automated Hydrogen Sulfide Analyzer is designed and manufactured completely in accordance with ASTM and IP testing standards.

4.The gas phase processor of semiconductor refrigeration has fast cooling speed.

5.It adopts the Cadon Fisher glass reaction test tube with easy operation.

6.Luer type sintering filter, filled with special adsorbent.

7.It adopts the Cadon H2S200 detection system for direct reading.

8.Quick Screwing gland self-sealing.
