A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can […]
Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation. In general, different materials differ in their Hardness,Macroscopic hardness is generally characterized by strong intermolecular bonds. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. There are 3 main types of Hardness measurements: Scratch
A tube furnace is an electric heating device used to conduct syntheses and purification of inorganic compounds and occasionally in organic synthesis. Its design consists of a cylindrical cavity surrounded by heating coils that are embedded in a thermally insulating matrix, Temperature can be controlled by feedback from thermocouples. Tube furnace two or more heating zones useful for transport experiments, It can
The term refrigeration means cooling a space, substance, or system to lower and/or maintain its temperature below the ambient one. Types of Refrigeration System There are three types of refrigeration systems they are as follows, Absorption Refrigeration. Evaporative Cooling. Thermoelectric Refrigeration. Mechanical refrigeration system In chambers we use Mechanical refrigeration system Mechanical Refrigeration System Mechanical refrigeration often referred to
The xenon test chamber uses a xenon arc lamp as a light source. It used for the study of weathering and accelerated aging testing by closely emulating true environmental conditions. Controlled product degradation study (weathering), using varying light spectrum, temperature, and moisture. Used to evaluate the weather resistance of the test material or samples.
The three-zone type thermal shock test chamber. Sample is placed in the test chamber, more extreme temperature than test temperature can be set in high-temperature chamber and low-temperature chamber. During low temperature test, cold chamber door open, and low-temperature chamber working together with test chamber. When converted into high-temperature test, cold chamber door closed, hot

Ultrasonic bench cleaning is a process that uses ultrasound to agitate the fluid. The ultrasound can be used with just water but use of appropriate solvent for the object to be cleaned and the type of soiling present enhances effect, Cleaning normally lasts between 3 to 20 minutes depends on the object has to be

These tests consist of condensation of evaporated, volatile components from interior equipment on vehicular window glass, the front windscreen. Determination of the fogging characteristics (liquid raw materials, paste and solid raw materials contained in the materials from which they are made) can be conducted using the following methods: fogging value – quotient of reflectometer 60°
Salt spray test or salt fog test is a standardized and popular corrosion test method, which is used to check corrosion resistance of materials and surface coatings, Usually, the materials to be tested are metallic and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal. Although we can check on

Ultrasonic nebulizer is a type of cool-mist Humidifier which uses anultrasonic vibration to disperse a cool mist of water into the air. As it moves, it breaks up the water into tiny particles. Ultrasonic humidifiers use a piezoelectric transducer to create a high frequency (1-2 MHz) mechanical oscillation in a film of water. This forms an extremely
