Operation Method of Cassette Moisture Analyzer

  Moisture Analyzer Manufacturer  introduces this news to you. The high-precision standard piston-type burette and anti-diffusion titration head of the Karl Fischer moisture analyzer ensure high-precision potentiometric titration. The push-fit design of the burette makes it easy and quick to replace at any time. Principle of   Moisture Analyzer In 1.1935 Karl-Fischer (KarlFischer) first proposed the method of measuring moisture using capacity analysis, this method is the visual method in GB6283 "Determination of Moisture Content in Chemical Products". The visual method can only measure the moisture of colorless liquid substances. Later, it developed into the electricity method. With the development of science and technology, the coulomb counter and the volume method are combined to introduce the coulomb method. This method is the test method in GB7600 "Determination of Moisture Content of Transformer Oil in Operation (Coulomb Method)". The classification visual meth...

What Are the Components of a Balance?

  A balance scale is a tool used to weigh mass. One end of the scale is a weight. A metal block or piece of metal is placed on one end of the balance as a weight standard. At the other end is a tray for the items to be weighed.Modern balance, more and more precise, more and more sensitive, more and more kinds. As we all know, there are general scales,   precision scales 0.01g , constant analytical scales, micro analytical scales, semi-micro analytical scales, and so on.Let's look at the details. The components of a balance Common plate balance is mainly composed of column, beam, hanging system, base and brake device.The column is fixed vertically on the base to support the beam.The lower part of the column is provided with a dividing plate, and the top is provided with a bracket to support the beam when the balance is not working.There is a central knife in the middle of the beam.When the balance works, the middle knife is used on the knife support connected with the top of th...
