EN/IEC61000-4-2,ISO10605 EMC ESD Simulator

ESD Protection For Power Supply Units(EMC ESD Simulator)

The phenomenon of static electricity and electrostatic discharge (ESD) is a common phenomenon in daily life and is not unfamiliar to people. Static electricity is mostly harmful to daily life and industrial production, but it has been used in production, such as electrostatic copying, electrostatic spray painting and electrostatic dust removal.     EN/IEC61000-4-2,ISO10605 EMC ESD Simulator  The harm of static electricity to electronic equipment and systems has attracted more and more attention. The rapid development of field effect devices and MOS integrated [...]

Vickers Hardness Tester

What Are The Factors That Affect The Vickers Hardness Tester Value?

What are the factors that affect the hardness value of the Vickers hardness tester? This should be analyzed from the test principle and test conditions, specifically the following aspects: 1. Hardness tester: (1) Load mechanism: mainly includes the change of weight weight; the movement condition of the load mechanism; the friction force of the main shaft; the perpendicularity between the main shaft and the worktable; the change of the load lever arm ratio. (2) Indenter: It mainly includes two aspects: the geometric [...]

Differential Scanning Calorimeter(DSC)

Principle and structure of Differential Scanning Calorimeter(DSC)

Differential Scanning Calorimeter is a thermal analysis instrument that tests the thermal effect of substances in the process of heating or cooling. It can study the relationship between the physical and chemical change rate of substances and temperature, as well as the performance of certain physical and chemical properties of substances under the action of thermal energy. feature. Under the program control temperature, the temperature difference between the substance and the reference substance can also be measured as a [...]

Plastic Pipe Hydrostatic and Burst Testing Machine

Plastic Pipe Hydrostatic and Burst Testing Machine Maintenance Points

Pipe Hydrostatic and Burst Testing Machine Maintenance is a commonly used testing instrument with the advantages of stable performance, safe and reliable use, and easy maintenance. It needs to run for a long time during use, and certain wear and dirt problems will occur during operation, so regular maintenance is required.Maintenance of pipe hydrostatic testing machine:  The host and medium incubator must be grounded reliably. The safety valves in various main boxes of this machine have been adjusted before leaving the factory and [...]

General Reasons For Failure Of Thermogravimetric Analyzers(TGA) And Their Solutions

Thermogravimetric analyzer (TGA) is a device that measures the relationship between the quality of a sample and temperature or time under a program-controlled temperature and a certain atmosphere. In the early literature related to thermogravimetric method, a few researchers used to call it “thermogravimetric analysis method”. In fact, this title is inappropriate, because some samples will have almost the same mass during the experiment. or increase in quality. For example, when many metals are heated to a certain temperature [...]

Universal Testing Machine Testing Error Solution

  Universal testing machine is an important equipment in the research of material mechanics, but there are many kinds of testing machines, such as fatigue testing machine, etc. Different testing machines can meet different measurement needs. But no matter what type of testing machine it is, there will be errors in the measurement, so people will finally determine the precise value after many experiments.   The method of multiple experiments is used to avoid the error rate of the measurement value and [...]

Differential Scanning Calorimeter(DSC)

Differential Scanning Calorimeter(DSC) Considerations

  The Differential Scanning Calorimeter(DSC)  is a thermal analysis instrument that tests the thermal effect of a substance during the heating or cooling process. feature. Under programmed temperature, the temperature difference between the substance and the reference can also be measured as a function of temperature.     This product is mainly composed of heating system, temperature control system, signal amplification system, differential heating system and recording system. Some models also include an atmosphere control system and a pressure control system. The heating [...]

Carbon Black Content Analyzer

How does the carbon black content tester work? What are the precautions

​​ The Carbon Black Content Tester is a thermal analysis instrument mainly used to determine the actual percentage of carbon black content in plastic and polyethylene materials. The so-called carbon black test is obtained by gravimetric analysis of the sample after pyrolysis under nitrogen protection. So, how does the carbon black content tester perform the carbon black test? What are the specific methods of operation? These issues are often of concern to everyone. Let’s take a closer look at the [...]

Melt Flow Index Tester(MFR)

The Reason Of Melt Flow Rate(MFR) Meter Data Not Right?

Melt Flow Rate Meter (MFR) for resins, which is used to test natural, compounded and treated thermoplastics. In theory, if done properly, the two methods should produce the same test results. But with such important data, why are your measurements different from others?   Melt Flow Index Tester(MFR) Three factors that affect testing 1. Standard reference materials and proficiency test Some laboratories use Standard Reference Materials (SRM) to cross-validate the results of melt flow rate tests, and others have their own reference materials that [...]

Plastic Melt Flow Index Tester

Precautions for Operation of Melt Flow Index Meter (MFI)

The melt flow index meter is in charge of a special person. The test should be carried out in strict accordance with the operating procedures. It is strictly forbidden to do tests beyond the test range. After the test, the instrument should be restored to its original position to ensure that the next test is carried out normally. The working environment and conditions should meet the The specified requirements include relative humidity, room temperature, power supply voltage, and installation [...]
