Product Description

GD-SF04 Automated Houillon Viscometer for Kinematic Viscosity ASTM D7279 and ASTM D445


Introduction:
GD-SF04 Automatic Houillon Viscometer is an automated instrument for quickly determining the kinematic viscosity of oil products, designed and manufactured according to ASTM D7279. The instrument has the functions of automatic intelligent sampling, automatic testing, and automatic cleaning. It can work 24 hours a day, and its performance is comparable to imported similar instruments. The Patent No.: ZL 2016 1 0243188.1; ZL 2016 2 0328654.1.

Main Features:
1. The measurement speed is fast. The fastest time to get results in fast mode is 15 seconds, generally within 3 minutes, the whole process generally takes no more than 7 minutes.
2. High degree of automation. It can work 24 hours without interruption, and the sampling, measurement, cleaning, drying, result calculation, and repeatability calculation are all automatically completed. The measurement and cleaning and drying of the two viscosity tubes can be carried out at the same time.
3. It can measure many kinds of samples. It can measure transparent and opaque samples, including Newtonian liquids such as gasoline, diesel, kerosene, cutting fluid, heat transfer oil, additives, lubricating new oil and in-use oil.
4. Accurate measurement data. The instrument has the function of secondary precise quantification, automatically cuts the sample liquid column, accurately controls the sample volume, no longer depends on the micropipette quantification, which avoids the limitation and deviation of the pipette quantification, and ensures the accuracy of the data.
5. With the function of intelligent cleaning, the best cleaning mode can be automatically selected according to the measured viscosity value. Fully automatic double solvent cleaning, clean and fast, high cleaning efficiency and low cost. A cleaning process generally consumes no more than 10 ml of cleaning solvent.
6. The software is intelligent and user-friendly. Automatically select viscometer, reasonably allocate sample test order, add samples, delete samples, and give priority to testing at any time. Automatically recognize that the sample reaches the viscosity index calculation condition and automatically calculate the viscosity index.
7. It has many auxiliary functions. Constant calibration, temperature calibration, internal clock timing verification, automatic conversion of kinematic viscosity to Engler viscosity.
8. Software and hardware dual over-temperature protection, over-temperature alarm function, anti-dry burning protection function, cleaning solvent liquid level and waste liquid level alarm function.
9. It comes with double-layer and double-bath design, the temperature is more uniform, and different temperature points can be tested and cleaned at the same time without affecting each other. The viscosity tube can be quickly replaced without the need to empty the thermostatic bath.
10. Equipped with air source power cabinet, it can be cleaned immediately after the test is completed without waiting.
11. Adopting the miniature automatic sampling system, with low failure rate, smooth sample delivery and low vibration.
12. Adopting the PT1000 high-precision temperature sensor, the temperature of the constant temperature bath is stable and accurate, and the temperature control accuracy reaches 0.005ºC.
13. Adopting the high-end optical fiber amplifier and high-temperature encapsulated optical fiber, the signal stability and accuracy are higher.
14. Windows operating system, full English interface, simple operation, friendly man-machine interface, can be connected to the LIMS system, can be connected with a code scanner, and automatically enter sample information.
15. It can be equipped with a disposable filter, which greatly reduces the workload of operator on sample pretreatment.
