Electromagnetic drive stirrer

The electromagnetic drive stirrer generates a rotating magnetic field by rotating a magnet at the bottom, which drives the magnetic stir bar inside the container to rotate synchronously, thereby achieving liquid mixing. It is used for stirring solutions and homogenizing reactants in the laboratory, avoiding the risk of contamination associated with mechanical seals.
Selection
Select the length of the stirring bar based on the container size, choose the driving torque according to the liquid viscosity, and use polytetrafluoroethylene-coated stirring bars in highly corrosive environments. Ensure the solution temperature matches the stirrer's temperature resistance range, and select models with heating functions for high-viscosity liquids.

Selection of Coating Thickness Gauges Using Magnetic and Eddy Current Methods on Different Substrates
This article introduces two main methods for coating thickness gauges: the magnetic method and the eddy current method. When choosing a method, the key is to determine it based on the electromagnetic properties of the substrate.
Application of Coating Thickness Gauges in Electroplating Thickness Detection
Coating thickness gauges are used to measure the thickness of electroplated layers, primarily employing the electromagnetic induction method for measuring non-magnetic coatings on magnetic substrates, or the eddy current method for measuring insulating coatings on non-magnetic metal substrates.
Eddy current thickness gauge measures metal coatings on non-conductive substrates.
The eddy current thickness gauge utilizes the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil to induce eddy currents in the metal coating, thereby measuring thickness based on changes in coil impedance.
Laboratory Application Scenarios of Milligram Precision Balances
The milligram precision balance can accurately weigh up to 0.001 grams, primarily utilizing electromagnetic force compensation technology, and its performance is related to parameters such as repeatability and linearity error.
Eddy current thickness gauge detects coatings on non-ferrous metals.
The eddy current thickness gauge operates on the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil, which induces eddy currents on the surface of non-ferrous metal substrates.
The principle of measuring dry film thickness with a coating thickness gauge
Coating thickness gauges measure dry film thickness through non-destructive methods, with commonly used principles including electromagnetic induction, eddy current, and ultrasonic methods.
For electromagnetic vibration tables, whether to choose sweep frequency or fixed frequency testing standards for simulating transportation is crucial; do not make a random selection if you are unsure.
The electromagnetic vibration table is used to simulate transportation vibrations and test the durability of products and packaging. There are two types of tests: fixed-frequency and sweep-frequency. The selection should be based on the test objectives and relevant standards to avoid arbitrary choices. For new products, it is recommended to first conduct a sweep-frequency test to identify resonance points, followed by fixed-frequency tests as needed.
