Fangrui surface tensIon Meter test data deviation, how to solve?

During the experiment, the Surface Tensiometer test data deviates greatly, what should I do? How can I manually check the correction myself?

The Surface Tensiometer is a very precise instrument and equipment, and the test must be very meticulous. A small place will have a great impact on the data. When encountering a large data deviation, you can first check and confirm three points:

The first point is that the platinum sheet should be cleaned. The thin lens should be rinsed with running water first. After rinsing, it should be burnt with an alcohol lamp and put on the alcohol lamp. Burn the entire lens red. Remember that it is red, and put it on top. If it does not move for 20 to 30 seconds, it will burn the alcohol and burn the entire platinum plate red. If the alcohol burned is pure alcohol, it cannot be impure alcohol. Pure alcohol is this kind of pure alcohol with a concentration of more than 99.5%. Alcohol burns.

The second point is to wash the glassware, rinse it with running water, and then rinse it with the sample to be tested. Pour off the liquid after moistening the snow, and then pour the tested sample into it.

The third point is to calibrate the weight of the machine. There are steps for weight calibration in the instruction manual. Pay attention when calibrating. You can’t do other movements that are redundant. After hanging it up, wait for about 20 seconds and there will be a beep. After the sound is over, it will have a 600.0. Then take the weight down. At this time The number slowly returns to zero, which means the calibration is complete.

The last point, the measured water, it is recommended to go outside to get that kind of bottled distilled water for drinking, such as drinking distilled water, a bottle is three to five hundred milliliters, if this kind of water, its source is no problem, guaranteed, so I say this It is very convenient to know if the water is planted, because there is still no problem with the sample, and sometimes the customer uses other water to cause data deviation.

The above is for reference. If you still can’t solve the problem, you can consult the North and South Tide Technology.
