China Dark Petroleum Products Sulphur Content Tester Astmd1551

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.
