Ideal for air flow test and airtightness test

〇Features and Functions ・One-touch operation with icons enables easy operation even for beginners ・Test pressure and flow can be visually checked via waveform display ・Multilingual (English/Japanese/Chinese/Spanish) ・FTP function (Option) ・USB port for easy data management (data collection and backup) ・Flow Check (C-CHK) ・Flow Optimizer: Even if the pressure fluctuates, the flow rate is automatically corrected to that at the set pressure and displayed. 〇Two types of sensors realize measurement that takes advantage of their unique characteristics. Laminar Flow Sensor ・A wide range of flow rates available: F.S.10 mL/min to 100 L/min ・Stable measurement of pulsating flow rates, such as pump discharge flow rates ・Durable and robust with no moving parts Mass Flow Sensor ・Less susceptible to pressure fluctuations, achieving stable flow measurement ・No need to measure temperature since temperature compensation is unnecessary ・No need to compensate for changes in air pressure or environment ・Highly responsive and accurate mass flow sensor element

Cosmo’s Air Leak Testers began with the automation of cylinder block airtightness tests for engines in 1970. Our products are utilized in various fields including automotive parts, gas, water supply, medical, electrical, electronics, and food. In line with the overseas expansion of Japanese automakers, we began our own overseas expansion in 1983. We now have 24 sales and service offices in 13 countries. We are offering proposals and providing after-sales services overseas as in Japan. Currently, in order to support the electrification of automobiles, our products are being used for leak testing of parts for electrification such as battery cases and inverters as well as for fitting testing of electric power connectors. We are contributing to the efforts by our customers to prevent emissions of CO2. In various regions of South and Southeast Asia, we are donating pressure measuring equipment to technical schools to improve the quality of education and exchange technologies with local machinery manufacturers. We have been making every effort to help improve the industrial base through local manufacturing of high-quality leak testing equipment.
