In the electronic densitometer industry, how do customers choose an electronic densitometer that suits them? There are two main aspects to determine the electronic density meter that is suitable for them. This is the type of test sample and the functionality required for testing.
The electronic density meter is a kind of density meter which is currently used more. The main feature is that it combines the Archimedes principle with modern electronic technology. It is one of the methods for international common liquid density measurement. This method is compared with the traditional Weiss balance method. Compared with the pycnometer method, it has extremely convenient operation, and is not affected by factors such as thermal expansion and contraction, difficulty in cleaning, large scale mark error, narrow measurement range, cumbersome operation, etc. It has the characteristics of simple measurement, accurate measurement, stability and reliability.
Test sample type for electronic density meter customers:
Samples of customer test samples are often varied, and samples from different customers produce products. The samples are mainly divided into liquid and solid. The liquid and solid test methods are of course different in electronic density meters. Most of the electronic density meter is the type of sampling test. It only needs to take some samples and can be tested. Different from the glass tube densitometer, multiple sampling can be used to calculate the result. There are many types of solid testing, such as: rubber, plastic products, plates, sheets, tubes, wires, rods, seals, silica gel, polymers, polymers, and the same liquids, such as fluids, sticky Thick liquid, volatile liquid, corrosive liquid, high temperature liquid, suspension liquid, emulsified liquid, acidic liquid, alkaline liquid, salt liquid. Different samples require different electron density meters.
Functional test requirements for electronic density meters:
The electronic density meter test requirements, one is the accuracy, this is very important, generally one thousandth and one ten thousandth, of course, the higher the precision, the higher the price, the quality value is reflected, the accessories are imported is definitely better, this It is necessary to judge which one is needed according to the customer's own test results. The other is the test function of the instrument, such as want to measure the density value, and want to test the concentration value, or the water absorption rate, the environment requires constant temperature, these relative electronic density meters are another kind of upgrade, compared to these, the electronic density meter It can all be done.
