I. Executive standards:
GB/T6536-2010 ASTM D86 ASTM D 850 ASTM D 1078 - IP195 ISO3405 Determination of Atmospheric Distillation Characteristics of Petroleum Products, GB/T7534-2004 Determination of Boiling Range of Industrial Volatile Organic Liquids, Determination of Methanol and Alcohol Determination of distillation range of similar products and determination of boiling range of chemical reagents in GB/T615-2006.
II. Temperature measuring range:
0~400±0.01C, temperature measuring element: PT100 (original temperature measuring sensor of German B+B company), heating system adopts silicon carbide ceramic heater, which is safe and reliable, has long service life and fast heat dissipation.
III. Volume measurement range:
0- 100±0.01ml (infrared measuring cylinder reading system imported from the United States), each step is 0.01 ml, the instrument has its own measuring cylinder identification system, and does not need to replace the measuring cylinder to repeat the calibration, and comes with its own measuring cylinder chip identification.
IV. Distillation rate:
0~10ml/min can be set arbitrarily according to the experimental requirements, the normal rate is 4~5ml/min.
V. The temperature range of the condensing tube:
0~80±0.1 C; Antifreeze is added to the bath of compressor refrigeration (Danfuss imported from Germany), with a circulation system, the constant temperature is uniform, it is not volatile and flammable, and it does not need to be replaced for a long time. Using semiconductor and compressor mutual refrigeration unit, the cooling speed is fast.
VI. The temperature control range of the measuring cylinder:
0~80±0.1 C C; the recovery room is equipped with a fan to make the temperature uniform and good sealing, preventing air convection, and has its own measuring cylinder identification system, if there is no measuring cylinder, the instrument stops the experiment,
VII. Display function:
10-inch color LCD touch screen, full Chinese operation interface, the volume and temperature numerical parameters can be set arbitrarily, the temperature volume curve graph is displayed during the experiment, and the value of each set point is recorded, and at the same time, it has permission management Function, effectively avoid non-professionals to set the key parameters of the analyzer.
VIII. Operating system:
WindowsXP operating system, software can be upgraded,
IX. Safety functions:
cold bath liquid level sensing protection, automatic nitrogen fire extinguishing function, over temperature protection function, over volume protection function, over power protection function, no measuring cylinder can not start function, sensor damage prompt function,
X. Error correction:
The user can set the parameters according to the actual situation, which can quickly calculate the measurement results and errors. If the measurement results are out of tolerance, the analyzer will automatically re-measure, and the calibration must use standard oil samples to correct the errors after calibration.
XI.: Data acquisition:
The instrument automatically saves thousands of results, and comes with a 20-column dot-matrix micro thermal printer, which prints more quietly, quickly and clearly. The experimental results can be automatically printed.
XII: Correction function:
can correct atmospheric pressure, vapor temperature, sensor and measuring cylinder.
XIII: Interface output:
USB/232 communication interface communicates with the host computer, which is convenient to form a centralized management system. This machine can be connected to the LIMS system, or it can be switched between a computer and a touch screen to control the operation of the instrument (additional computer charges).
XIV: Voltage and power:
AC220V±10%, 50Hz, power: 1200W, must have a good grounding wire, use environment 10C~30C
XV.Volume and weight: 400×400×630(mm) and 50kg
