ASTM D7621 Apparatus for Hydrogen Sulfide in Fuel Oils

KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils

Overview

    KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils conforms to ASTM D7621 Standard Test Method for Determination of Hydrogen Sulfide in Fuel Oils by Rapid Liquid Phase Extraction. A weighed test specimen is introduced into a heated test vessel containing a diluent base oil. Air is bubbled through the oil to extract the H₂S gas. The air with the extracted H₂S is passed, via a vapor phase processor (Procedure A only), to an H₂S specific electro-chemical detector enabling the H₂S content of the air to be measured and the amount in the liquid phase to be calculated in mg/kg/ The filter cartridge is not required for procedure B.

Features

1. The air flow rate is measured and controlled by a digital mass flow meter;

2. The tester is designed and manufactured in full accordance with the requirements of ASTM 7621 , IP570 and ISO 8217 testing standards

3. Microcomputer control, automatic measurement, and automatic calculation of results;

4. Semiconductor refrigeration gas phase processor with fast cooling speed;

5. KAYCAN fisher type glass reaction tube, easy to operate

6. Luer type sintered filter, filled with special adsorbent;

7. KAYCAN H₂S200 detection system, capable of direct reading

8. Quick screwing cap for sealing
