Application of electrical components in low pressure test chamber

Electrical components usually need to operate at high altitudes or low atmospheric pressure, such as in alpine regions or aerospace. To test the durability of electrical components under low atmospheric pressure, the following methods can be used: Low pressure simulator: The use of a low pressure simulator to simulate air pressure at high altitudes or in aerospace environments. Install the electrical components in the simulator and test them in the simulator. Low pressure test chamber: Low pressure test chamber can simulate...

How to maintain the constant temperature and humidity test box when not in use?

When the constant temperature and humidity test chamber is not in use, the following measures should be taken for maintenance: Clean the box: Use clean wipes or paper towels to wipe the inside and outside of the box, especially the door sealing rubber pads and heaters, to ensure that the box is dry and clean. Power off: When the test chamber is not in use, the power should be turned off to avoid waste of energy and prolong the life of...

Lithium button battery needs to test the performance of the complete

What is a lithium button battery? Lithium button batteries are small, round batteries commonly used in small electronic devices such as calculators, watches and digital thermometers. It is called a "button cell" because its shape resembles a small, flat button. These batteries are known for their long life, high energy density, and ability to maintain a stable voltage output. They are usually made of lithium or lithium-ion chemicals and come in a variety of sizes and capacities. The most common sizes...

Coating thickness gauge: magnetic induction VS eddy current

Both magnetic induction thickness gauges and eddy current thickness gauges are used to measure film thickness, but they use different methods. The magnetic induction coating thickness tester is used to measure the thickness of the non-magnetic coating on the magnetic substrate, while the eddy current coating thickness tester is used to measure the thickness of the conductive coating on the non-conductive substrate. Coating thickness gauge: magnetic induction VS eddy current Different working principle Magnetic induction coating thickness tester uses magnetic induction principle...

Do you know ASTM G155 Xenon Lamp accelerated Aging Test?

ASTM G155 describes the general principles and operating procedures for xenon lamp devices used to expose non-metallic materials to conditions simulating outdoor weathering. This standard provides guidance for setting up, operating, and maintaining equipment and for conducting and evaluating exposure test results. The practice covers several aspects of exposure testing, including the selection and preparation of test samples, the control of exposure parameters such as irradiance, temperature, and relative humidity, and the evaluation of test results, such as changes in...

ISO 11341:2004 A brief introduction to exposure aging tests for xenon arc lamps with paint film

ISO 11341:2004 provides a method for determining the resistance of coatings and painted surfaces to artificial weathering and exposure to artificial radiation using filtered xenon arc radiation sources. This standard applies to coated and painted surfaces intended for external exposure. This standard sets out general principles for testing procedures, including selection of test samples, preparation of test samples, exposure conditions and evaluation of test results. Exposure conditions include irradiance, temperature, relative humidity, and spectral power distribution of xenon arc sources. Exposure...

Sand dust test chamber

Sand dust test chamber  Sand Dust test chamber  is also known as dustproof test box, suitable for all kinds of accessories and parts to do dustproof and dustproof test, test parts including lights, instruments, electrical dustproof sleeve, steering system, door lock, etc.The equipment is driven by a fan to blow a certain concentration of sand dust at a certain flow rate over the surface of the test samples, so as to evaluate the ability of these test samples (equipment) to defend...

Hot cold impact testing machine eight safety protection measures

Hot and cold impact testing machine eight safety protection measures Hot and cold impact testing machine although the application range is wide, but many enterprises are not willing to buy, because its price is relatively expensive, so once bought, we should pay attention to maintenance, the following points are introduced: Hot and cold impact testing machine safety protection measures: 1, hot and cold impact testing machine safe and reliable grounding protection device. 2, power supply undervoltage, lack of phase protection. 3, heater short circuit,...
