I. Instrument Overview

The HSY-511A-2 Mechanical Impurity Tester is designed and manufactured in accordance with GB/T 511-2010 "Determination of Mechanical Impurities in Petroleum and Petroleum Products and Additives." It is suitable for measuring the mechanical impurity content in various hydrocarbons, heavy oils, lubricants, and additives in petroleum products. Equipped with an oil-free maintenance-free vacuum pump and a metal bath constant temperature funnel, the main unit of the instrument integrates all functions, eliminating the need for external vacuum pumps or water baths, making it energy-efficient and environmentally friendly.

II. Main Functions and Features

1. 7-inch color touchscreen with a resolution of 800×480, providing an aesthetically pleasing and user-friendly interface.

2. Utilizes a 32-bit microprocessor as the main control core, featuring a new generation graphical intelligent operating system with built-in user instructions.

3. Built-in formulas for automatic calculation of test results, capable of storing 90 sets of test data.

4. Two independent PID temperature control channels for precise regulation of the constant temperature funnel.

5. Employs a built-in oil-free maintenance-free vacuum pump with programmed減壓抽濾 (pressure reduction filtration).

6. The specially designed vacuum pump structure ensures that even if oil samples are drawn into the vacuum pump, the instrument remains undamaged, minimizing accidental losses.

7. Compact design, occupying only 1.5 A4 paper sizes of desktop space.

8. RS232 interface for connection to LIMS systems.
