Purpose:
PT-D1551-387 Dark Petroleum Products Sulphur Content Tester (Tubular Oven Method) is designed and made as per the National Standard GB/T387 "Test Methods for Sulfur Content of Dark Petroleum Products (Tubular Oven Methods)" and ASTM D 1551. It is suitable to determine sulfur content of dark petroleum products. Place sample in a quartz boat and completely burn sample in the high temperature air at a stipulated flow rate. Absorb sulfurous anhydride and sulfuric anhydride produced from combustion using peroxide and sulfuric solution. Then make titration for sulfuric acid produced using sodium hydroxide solution.
Technical characteristics
- The instrument is mainly composed of tubular oven, oven temperature controller, flow meter, and display.
- Adopt microprocessor to form the intelligent controlling system, it can control determination time, oven movement, and alarm system automatically.
- After preset oven moving mode, the oven can move, stop moving and return back to initial state automatically as per the requirement of test procedures.
- It has two parallel tubular ovens in horizontal type, so it can make determination for 2 samples at the same time. It is efficient, accurate and reliable.
- Equipped with air source and a joint for outer air source, so you can use inner air source of the instrument or outer air source.
