Product features:
1. The distillation test can be completed with one click, and the detection process complies with the standard regulations, with good repeatability and long-term contact
2. There are 16 preset parameters for selection, and the preset parameters can be modified to meet special requirements
3, color touch display, keyboard control, program control and other modes are easy to operate
4. Built-in miniature thermal printer automatically reports the test results
5. Adopt German vitreous temperature sensor for accurate and reliable data
6. The distillation heating adopts low pressure (24V) centralization, which is energy-saving and safe
7. The infrared measuring cylinder reading system adopted in the United States has high resolution, so that the recovery reading can be accurate to 0.01 ml
8. The built-in German atmospheric pressure detection module can automatically complete the pressure correction, so that the experiment is not affected by atmospheric pressure changes
9. The cold bath constant temperature adopts the built-in small circulation mode, and uses the German Danfoss compressor, which is reliable and has no lag and is not easy to damage.
10. Rapid cooling of distillation chamber shortens the waiting time and improves the efficiency
11. Infrared photoelectric liquid level detection and dark room automatic constant temperature are not affected by environmental factors
12. Automatic detection function of initial distillation point, final distillation point and dry point
Technical parameter:
1, temperature range: 0 ~ +400℃ ±0.01℃
2. Correction function: it can correct atmospheric pressure, steam temperature, sensor and measuring cylinder.
3. Display: 10-inch color LCD touch screen. The operation interface is fully Chinese, and the volume and temperature parameters can be set arbitrarily. During the experiment, the temperature-volume curve chart is displayed, and the values of each preset point are recorded. Meanwhile, the system has permission management function to effectively prevent non-professionals from setting key parameters of this measuring instrument.
4. Temperature correction: automatic correction and programmable correction
5. Heating method: Electric heating unit
6. Temperature measuring element: PT100 (original temperature measuring sensor from B+B Company, Germany)
7. Distillation rate: 0~10ml/min can be set arbitrarily according to experimental requirements, and the conventional rate is 4~5ml/min.
8. Constant temperature range of cold bath: -10-- +70℃
9. Data storage: 100 test results
10. Volume detection range: 0~100mL ±0.01mL (American infrared cylinder reading system) each step is 0.01 ml, the instrument has its own cylinder identification system, no need to replace the cylinder for repeated calibration, and has its own cylinder chip identification.
11. Interface output: It can be connected to the computer without cable, or the instrument can be operated by switching between the computer and the touch screen (additional charge for the computer).
*12. Condenser tube temperature range: 0~80±1℃; Compressor refrigeration (Danfoss, Germany) The bath is filled with antifreeze and equipped with a circulation system for constant temperature uniformity, which does not volatilize or ignite, requiring no replacement even after long-term use. It adopts a semiconductor and compressor mutual cooling unit, achieving rapid temperature reduction.
*13. The temperature control range of the measuring cylinder is 0~80℃; the recovery chamber is equipped with a fan to make the temperature uniform and have good sealing to prevent air convection, and has its own measuring cylinder identification system. If there is no measuring cylinder, the instrument will stop the experiment.
*14. Operating system: Windows operating system, software can be upgraded
*15. Safety functions: cold bath level sensor protection, automatic nitrogen fire extinguishing function, over temperature protection function, over volume protection function, over power protection function, no cylinder can not start function, sensor damage warning function.
16. Error correction: Users can set parameters according to the actual situation, and they can quickly calculate the measurement results and errors. If the measurement results exceed the limit, the measuring instrument will automatically re-measure. The calibration must be carried out with standard oil samples to correct the errors.
17. Data acquisition: The instrument automatically saves the results, and has a built-in 20-column dot matrix micro thermal printer, which prints more quietly, quickly and clearly. The experimental results can be printed automatically.
*19. Voltage and power: AC220V±10%,50Hz, power: 1200W, must have a good grounding wire, and the operating environment is 10℃~30℃.
20、Volume and weight: 400×400×630 (mm) 50kg.
