According to standard: ASTM d 445,ASTM D446,ISO3104,ASTM D7279; It meets the requirements of GB265-88, GB 11137-89 on repeatability and reproducibility.
Viscosity tube: 2 branch broken tube type viscosity tube, the inside diameter of capillary tube according to the custom.
Measurement range: two viscosity tubes, each 10 times the measurement range of two 100 times, According to user requirements in the motion viscosity between (2 ~ 1500) mm2/scustomized, which can measure transparent and opaque liquid.Temperature of constant temperature tank: normal temperature ~ 100℃. Temperature control error:0.01℃@40℃, 0.02℃@100℃above
Timing: the timing precision is 0.01s, and the maximum timing is 999.99s.
Detection mode: photoelectric
Constant temperature tank volume: 3.5L
Temperature detection components: PT500 platinum resistance
Aerodynamics: with vacuum pump, do not need to provide compressed air.
Thermostatic liquid: methyl silicone oil
Injection mode: microtubette, disposable nozzle
Repeatability: ≤0.68%.
Reproducibility: 2.2%.
Accuracy: 1.0%.
Analysis time: the time to analyze a sample consists of the following three partsA) sample injection and temperature balance: it refers to the time from sample injection to sample arrival at the first detector, which takes about 1 ~ 2min.B) sample dropping time: the time between the sample flowing through the upperdetector and the lower detector is 30-300 seconds, most of which is within 2 minutesC) cleaning and drying time: generally not more than 3 minutes.
Cleaning solution: the first round of cleaning generally USES solvent oil, gasoline, diesel and other high cleaning efficiency of the solvent, the second round USES alcohol, petroleum ether and other volatile solvents.You can also use only highly volatile solvent oils, such as 120# solvent oils, petroleum ether, etc.
