Ozone aging test chamber can be used for rubber products, such as vulcanized rubber, thermoplastic rubber, cable insulation and sheath, etc., to test the change degree of cracks on the surface of the sample or other properties of the sample at the predetermined time in the constant temperature chamber containing a closed air and ozone without light exposure under continuous or intermittent static ...
Introduction Digital oscilloscopes are essential instruments for signal analysis, visualizing waveforms, and carrying out measurement tasks in the fields of engineering and the sciences. They are useful in a variety of settings on account of the complex features they provide, the remarkable accuracy they offer, and their versatility. In this article, we’ll take a look at how digital oscillos...
I.Measurement principle of Lux Meter: Light photovoltaic measurement principle: LMS-6000 is a direct conversion of light energy into electrical energy of the photovoltaic components. When the light is shone on the surface of the selenium photovoltaic cell, the incident light passes through the metal film 4 to the boundary between the semiconductor selenium layer 2 and the metal film 4, creating a ...
The glow wire test apparatus simulates that parts of insulation materials or other solid combustible materials that are prone to flame propagation inside the equipment may ignite due to the glow wire or glow element. Under certain conditions, such as fault current flowing through wires, component overload, and poor contact, certain components may reach a certain temperature and cause nearby parts...
UV aging test chamber is the result of accelerated weathering test on materials to obtain the weathering resistance of materials. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation and darkness in the natural environment and climate, and combine these environmental conditions into a cycle by reproducing them, and let it automatically c...
Glow wire testing can be used to assess fire protection in electrical equipment. It is intended to simulate what an over-heated component may cause a fire and test the combustibility of plastic materials. The test uses a heated wire to simulate an overheated element and measure the reaction when the plastic material comes into contact. If the material does not ignite when in contact with the heate...
Introduction Goniophotometry is a common method of measuring in the study and design of artificial lighting. It allows for a precise evaluation of the light’s angular dispersion from a given source or fixture. The performance, features, and behavior of lighting systems may be better understood with the use of goniophotometric data. The purpose of this article is to introduce readers to the f...
Introduction The success of a mission, the efficiency of operations, and the safety of military personnel all depend on the dependability of sensitive electronic equipment. Military systems are especially vulnerable to voltage surges and transient disturbances, which may cause equipment failure, data loss, and breaches in operational security. Important military equipment may be shielded from dama...
The needle flame tester is applicable to the research, production and quality inspection departments of electronic equipment and its parts and components, such as lighting, low-voltage appliances, household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connecto...
