There are many different brands of color spectrophotometers on the market, and even within the same brand, there are multiple products available. The handheld and desktop types are the most popular categories, but what are the differences between these two types? Portable Colorimeters – also known as Portable spectrophotometers Can directly read data and connect to a computer through softwa...
I. Introduction of Surge Generator Surge generators are important equipment in electrical systems. Their main function is to simulate high-voltage pulses or instantaneous voltage fluctuations to test and evaluate the effectiveness of different surge suppression systems. These high-voltage electrical devices mainly serve to prevent transient voltage fluctuations from damaging electrical systems, th...
What is Damped Oscillation: Damped oscillation is a type of non-harmonic motion commonly seen in systems such as spring oscillators and pendulums. It is a vibration in which the amplitude gradually decreases over time due to the presence of factors such as friction and resistance, also known as damping. The vibrating system continuously overcomes external resistance and consumes energy, causing th...
What is Coupling and decoupling? Coupling is the energy exchange linkage between two circuits or two parts in one circuit, enabling energy to be transmitted from one circuit to another or from one part to another. Decoupling is the prevention of energy feedback from one circuit to another, to avoid unpredictable feedback reactions, resulting in abnormal operation of the next level amplifier or oth...
The High and Low Temperature Termal Shock Chamber is the main equipment of modern reliability laboratories, which simulates the changes in cold and hot environments for testing, and is used for cold and hot cycles of various materials and environmental stress tests under high and low temperature impacts. The physical changes and material properties of the product after the environmental test of t...
Transformer preventive testing, a crucial component of power equipment operation and maintenance, has long been given priority by the state. Practical experience suggests that following inspection regulations enables the inspection to make full use of its role and safeguard the safe operation of power equipment. With the enhancement of insulation level and the continuous advancement of computer te...
The High Temperature Pressure Jet Waterproof Test Chamber is an important experimental equipment, usually made of materials such as stainless steel or domestic steel plates. It can simulate high-temperature and high-pressure conditions in real environments, and conduct reliability testing and performance verification on products in experiments. Its main function is to spray high-pressure and high...
Capacitance refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According ...
