Precautions when using the density tester.

Density meter is abbreviated as liquid density tester, which is an instrument for measuring density value. The common density meter is a desktop electronic density meter, which is a new type of electronic density tester based on the principle of Archimedes buoyancy method combined with modern technology. Its advantage is that the test degree is very high, the accuracy is up to one ten thousandth, the performance is repeatable, repeated use will not affect the performance of the density tester, the service life is long, and it can be used for many years and is loved by consumers. Introduce the common problems and usage steps of the next density tester

Precautions for the use of density tester

If the screen is not bright or black after turning on the host, you can check whether the density tester itself has power, and check whether the power supply is normal. If the interface is abnormal, please check whether some key operations respond and restart the device. When the test result is not zero, check whether the current curve value (Kv) setting is zero, check whether there is monochromatic light in the colorimetric cell of the density tester, and check whether all the same samples are taken from containing blanks.If the measurement result displayed by the density tester is unstable and the value fluctuates up and down, please check whether there is any suspended liquid on the outer wall of the test tube of the density tester. Adjust zero with air, observe whether the light transmittance is stable; whether the density tester is preheated before colorimetry; check whether the colorimetric method is the turbidity of the solution, and observe whether there is a suspension.

How to use the density tester correctly?

First, place the measuring cup with the sample on the measurement placement plate and subtract the weight of the hook. Then hang the standard weight on the hook, completely immerse it in the liquid to be tested, and display the density value. The density meter calibration adopts the direct comparison method, that is, the standard density tester and the working density meter are immersed in the same standard solution at the same time, and their scale indication values are directly compared to obtain the working density tester calibration. In order to avoid the influence of liquid surface tension changes as much as possible, the "overflow method" is used for calibration. The so-called overflow method is to use an overflow cylinder to overflow a layer of liquid surface to form a new liquid surface, and then perform calibration.
