[INQ. NO. 2507M30] With over 30 years of technical expertise and know-how, Sunil Leak & Flow designs and manufactures precision inspection and automated assembly equipment for various fields including the aviation and automotive sectors, medical devices, and industrial sites.
Through its leak testers, performance testers, flow testers, and automated assembly systems, the company provides top-level precision measurement solutions that offer customized performance, ease of use, and cost-effectiveness.

Leak Detector
The AFT-4000HK-R is a high-precision air leak tester that adopts the mass flow sensor method, which dramatically resolves problems in leak volume management that occur in differential pressure-type leak testers. It can precisely measure leak rates in cc/min units, enabling systematic product-quality management. At the same time, it can stably control test pressure fluctuations through a servo regulator, making it flexible for both small- and large-scale production lines.
This model’s key features include real-time graphical display of leakage volume and pressure status for visual monitoring. It can realize automatic classification and output by dividing leakage sizes into large, medium, and small ones. Additionally, different pressure conditions can be set for each work process, enabling adaptation to various product groups. It has various features designed to enhance user convenience and productivity such as air charge curve settings, rapid pressurization and pressure unit conversion.

Differential Pressure Leak Detector
The AFT-123HK-R is a differential pressure leak detector designed to minimize its size. It is a high-performance device developed for easy and rapid leak detection. Its compact and lightweight structure allows it to operate efficiently even in small spaces, providing high space utilization and flexibility for convenient use at various industrial sites. In particular, this product is powered by a high-speed 32-bit CPU, delivering outstanding performance at leak detection sites that require fast data processing and response times.
Additionally, this product’s 32-bit analog-to-digital (A/D) conversion function accurately converts even minute pressure changes into digital signals. Therefore, it can ensure precise measurement results, which is a critical factor in quality inspection processes.
Furthermore, up to 32 channels of various measurement conditions can be preset and stored for each product, thereby enhancing both convenience and productivity during repetitive tasks even when measurement conditions vary by product. The device also features RS-232 serial communication functionality, thus enabling connectivity with external devices or PCs, and facilitating the construction of automated systems for remote control and data transmission.
As such, the AFT-123HK-R combines precise measurement performance, fast processing speed, diverse setting functions, and automation connectivity, providing an optimized solution for quality control lines with diverse inspection conditions in small spaces.
