Air Leak Testers

Air Leak Tester is an automatic leak detector to detect the minute change of differential pressure and determine OK or NG by increasing air pressure or evacuating the vacuum for the leakage of parts and finished products which are required to be air tight. COSMO INSTRUMENTS's own analysis system will detect minute differential pressure by leakage with high sensitivity. It can judge minute leakage in a short time. The specialized staff will provide support around the world, including Thailand.

Waveform Analysis System

"Movelet", a waveform analysis system, was developed for the purpose of automatic tests in lines related to sounds and vibrations. COSMO INSTRUMENTS's own analysis method solved the current problems of waveform analysis technology, for which human's senses and analysis results are different. It will realize the judgment close to that provided by a human's senses.

Leak Master

Leak Master is an accurate, stable and convenient generator of minute leakage. It can conduct a sensitivity check in dairy inspection and volume equivalent measurement easily. It can be produced with your desired test pressure and leak volume to utilize as an ideal determination device. There are many delivery results in Japan, Thailand and in the world as the leak detecting standard.

Accessories

We prepared the accessories and peripheral equipment which maximize the performance of the COSMO Air Leak Tester. We have a Master Chamber to solve the problems, such as dealing with various kinds of products in the master's comparison system and Exhaust Valve Units to prevent the invasion of foreign substances, such as water and oil, to prevent the tester's malfunction.

Leak Master LM-1C

Leak Master "LM-1C" is suitable for daily inspection of air leak testers. The sensitivity of leak volume can be checked certainly and easily. There are many results that have been delivered in Japan and Thailand that set LM-1C as the leak standard. It can be produced with your desired test pressure and leak volume to utilize as an ideal determination device. The change of leak volume is small, and it can be used for a long time. A traceability certificate also can be issued.

Differential Pressure Decay Air Leak Tester LS-R902

LCD touch panel and completely changed the operation method to be intuitive and easy to understand. The measuring screens have 6 types of screens according to the usage and situation, and the language can be chosen from 7 languages. Industrial Field Network supports smooth communication with PLC with fewer cables. Test results can be output to the network.

Differential Pressure Decay Air Leak Tester LS-R700

The expressive power increased by adopting a colour liquid crystal display. Moreover, we completely changed the operation method to be intuitive and easy to understand. The measurement display has 3 types and can be switched according to the situation. The language display can be switched to be Japanese, English, or Chinese, so the air leak testers can be used immediately in factories around the world including Thailand.

Air Leak Tester for small and sealed products LS-R740 (ZL)

This Air Leak Tester is suitable for work requiring IP standards and waterproof protection level and waterproof tests of parts and finished products. It measures the pressure change by leakage that has gotten into the sealed products by putting the test object into a capsule and applying pressure. It is displayed with icons, excellent in operability and equipped with a USB port, which makes data collection easy. It has a function to switchthe display language to Japanese, English, or Chinese, so it can be used in factories around the world, including Thailand.

Waveform Analysis System Movelet

The waveform analysis system "Movelet" analyzes and quantifies the waveform of sounds and vibrations generated from test objects and makes judgments close to those achieved by human's senses. The crack tests also can be conducted from the tapping sound. "Movelet" performs emphasis processing on the specific frequency band with an original analysis system called "Fluctuation transformation" and enables inspection in production sites with a lot of noise.

Master Chamber MC series

When putting test pressure on work, the air temperature rises rapidly by insulation change, and it will be an error factor of minute leak measurement. Master Chamber can match the temperature characteristics of work by changing the ratio of volume and surface area with the number and arrangement of fins and eliminate error factors by temperature change. It enables measurements excellent in repeatability without volume change.

External Exhaust Valve Units G3-ME

When water or oil are left inside work, or it is used in a testing device which is used in combination with water-dunking, these foreign substances might get into the air leak tester exhaust, and it might cause a malfunction. By setting up the exhaust valve unit close to the work, the malfunction can be prevented before it happens. It adopted an air-operated valve with a special structure which is resistant to solid waste. The movement of the exhaust valve can be controlled by the tester body.
