Automatic Distillation Range Tester

I. Product Introduction

Thank you for choosing the LC series fully automatic distillation range tester. The instrument is designed and manufactured according to the test methods of GB/T 18255-2000, GB/T 7534-2004, GB/T 3146.1-2010 and GB/T 18589-2001. It is suitable for the distillation range determination of natural gasoline (stable light hydrocarbons), motor gasoline, aviation gasoline, jet fuel, special boiling point solvents, naphtha, kerosene, coal tar, diesel, gas oil distillate fuels and similar petroleum products.

II. Safety Precautions

1. Electrical safety: the instrument operates on AC 220 V. Before use, the laboratory power socket must be properly grounded and the instrument housing reliably earthed; when the instrument is not in use, the power plug must be removed.

2. Fire risk: during heating, there is a risk that the distillation flask may break and cause flammable liquid to leak and ignite. A fire extinguisher must be kept nearby when using the instrument, and operators should stay away from the heating furnace area during the experiment.

3. Operation safety: the instrument must be attended by a dedicated person during operation to respond to emergencies at any time.

III. Product Features

1. The display uses an original 10.0-inch 1920×1080 pixel HD LCD screen with a full Chinese operation interface, providing fine, intuitive and elegant display.

2. Operation uses a capacitive touchscreen, which has the advantages of no mechanical wear, dust and water resistance, radio frequency interference resistance and long service life.

3. Historical data is stored in a FLASH data memory that can store 10,000 historical records.

4. Temperature measurement and control use an original imported PT100 platinum resistance temperature sensor from JUMO, Germany, combined with a high-precision high-speed AD converter, making temperature acquisition faster and more accurate, easily capturing even step temperature changes.

5. The titration monitoring system adopts advanced infrared optical detection technology with a high-precision photoelectric sensor to precisely capture every drop of sample, with high automatic liquid level tracking accuracy.

6. Semiconductor refrigeration technology is used to automatically control the condenser tube temperature and the recovery chamber temperature.

7. A high-precision temperature sensor precisely measures the steam temperature.

8. The instrument automatically controls the electric furnace power, automatically tracks the liquid level, automatically controls the temperature of the recovery chamber and condenser tube, and performs automatic calculation.

9. Built-in thermal printer automatically prints test results.
