Model A1075 Dual‑Unit Water Content Tester for Petroleum Products is designed and manufactured in accordance with the requirements of national standard GB/T260. It is suitable for determining the water content in petroleum products. It can also be used to test the water content in greases according to the test method specified in GB/T512.

he instrument is widely used in:

• Petroleum laboratories
• Oil refineries
• Fuel production plants
• Chemical industries
• Quality inspection institutions

It is suitable for testing water content in:

• Crude oil
• Fuel oil
• Lubricating oil

Testing Standards

The A1075 Water Content Tester is designed according to international petroleum testing methods:

• ASTM D95 — Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation
• Related petroleum laboratory testing methods

ASTM D95 is widely used for determining water content in petroleum products by distilling the sample with a water-immiscible solvent and measuring the collected water volume.

Working Principle

The A1075 uses the distillation method for water content determination.

Testing process:

1. Petroleum sample is mixed with solvent.
2. The mixture is heated to generate vapor.
3. Water and solvent vapor are condensed.
4. Water separates from solvent due to density difference.
5. The collected water volume is measured through a graduated receiver.

The final result represents the water content of the petroleum sample.
