HK-0689A Sulfur and Nitrogen Analyzer

Overview
The HK-0689A Sulfur and Nitrogen Analyzer complies with the requirements of test methods including SH/T 0689, ASTM D5453, SH/T 0657, ASTM D4629, and ASTM D5762. It is suitable for determining the total nitrogen and total sulfur contents in crude oil, distillate oil, liquefied petroleum gas, plastics, petrochemical products, food, and water.

Features

1. Key components are imported parts. The cooling fan switches on and off automatically, eliminating the need to wait for shutdown after sample testing.
2. The instrument features high sensitivity, good repeatability, low noise, and a wide linear range.
