Heated Electromagnetic Agitator

The heated magnetic stirrer operates by using an electromagnetic field to rotate a magnetic stir bar inside a container, achieving mixing while controlling the temperature with a heating plate. It is used for solution reactions requiring constant temperature mixing in laboratories and is commonly employed in sample preparation processes in fields such as chemical engineering and materials science.
Selection
When selecting, consider matching the heating temperature range and stirring capacity with experimental requirements, pay attention to the material's corrosion resistance, observe stirring stability, check temperature control accuracy, and ensure comprehensive safety protection features.

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.
Comparison of Dual-Principle Instruments: Magnetic Induction vs. Eddy Current for Coating Thickness Measurement
This article compares the principles of two coating thickness gauges. The choice of method depends on the substrate material: magnetic induction is used for magnetic metals, while eddy current is applied for non-magnetic metals.
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.
Magnetic thickness gauge measures the thickness of coatings on steel surfaces.
Magnetic thickness gauges are used to measure the thickness of non-magnetic coatings on ferromagnetic substrates such as steel, based on the principles of magnetic induction or changes in magnetic attraction. Prior to use, calibration should be performed according to relevant standards, and attention should be paid to factors such as substrate characteristics, workpiece shape, and surface conditions that may affect the measurements.

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.
