Leak testing is a process used to detect manufacturing defects which helps verify the integrity of products and improve consumer safety.  For example, the automotive industry consistently uses leak testing to verify that assembly operations were completed properly and subcomponents are leak free. Leak tester is the equipment that used to test whether a product such as package is leaking or not. There are many types of leak testers in the market. Most common types are gas leak testers, liquid leaking tester, etc.

Helium is a chemical element with symbol He and atomic number 2. It is a rare atmospheric gas which is colorless, odorless, tasteless, nontoxic, nonflammable and only slightly soluble in water. The concentration of Helium in the atmosphere by volume percent is 5.24 x 10-4. Its boiling points and melting points are the lowest among all the elements and it exists only as a gas except in extremely cold conditions. Helium is principally shipped and used in either gaseous or liquid form for nuclear reactors, semiconductors, lasers, light bulbs, superconductivity, instrumentation, medical applications, cryogenics, MRI and R & D laboratory research.

Gaseous helium is inert, colorless, odorless, noncorrosive, and nonflammable. Helium is the lightest rare gas. Helium is a monatomic chemically inert gas. It will not react with other elements or compounds under ordinary conditions. Since helium is noncorrosive, special materials of construction are not normally required. Vessels and piping must be selected and designed to withstand the pressure and temperatures involved and comply with applicable codes and regulations.
Ultrasound Systems is a special medical device used in ultrasonography for diagnostic purpose. Ultrasonography, commonly known as ultrasound, is a popular medical imaging technique used in diagnostics, and which uses high-frequency sound pulses and their echoes to specific body regions. Ultrasonic waves are specifically helpful in visualizing or imaging subcutaneous or internal body structures including muscles, tendons, vessels, joints or internal organs for any pathology or lesions.
A Variable Displacement Pump is a type of mechanical-electrical motor placed in a fluid channel. Built either to generate electrical power from the natural flow of fluid past it or to apply mechanical force to make stationary fluid flow in a pipe gives the variable displacement pump a dual use — adjustable capability. Such pumps have versatile applications because they can be set to capture the maximum amount of hydraulic fluid energy as the velocity of fluid flow in a channel dynamically changes, or they can be switched to applying mechanical energy powered by electricity to increase fluid flow.
Remote Patient Monitoring Products is the system to measure vital signs remotely, and to manage escalation strategies based on pre-determined rules applied on the measured data. Data transfer can be achieved via wireless communication means and or data transfer over other media, such as a telephone or computer network or via an optical link. Remote Patient Monitoring Products improves patient visibility and interaction, which is beneficial at any point of the care continuum.
Phosphonates are a class of chelating agents and scale inhibitors, which structurally have the phosphonic acid group –PO3H2 in common. They are used in household cleaning products, personal care products, institutional cleaners and industrial cleaning processes, and as water treatment additives in various applications. The most common phosphonates are aminotris(methylene phosphonic acid) (ATMP), 1-hydroxyethylidene diphosphonic acid (HEDP) and diethylenetriamine penta(methylene phosphonic acid (DTPMP).
