High quality compatible with a water depth of 300m (30 atmospheres) and a durability of 10,000 attachment and detachment cycles! Added a power layout compatible with 38mm2 cables.

In addition to 4-core and 7-core options, the single-core power layout has finally been commercialized. The cumbersome potting process is unnecessary, and the push-pull coupling method makes handling easy. The open-face seal structure prevents water from entering the connector even in a non-coupled state. It has achieved a durability of 10,000 mating cycles. 【Applications】 Submersible pumps, ROVs, underwater lighting, marine-related facilities (buoys, etc.), underwater cameras, underwater defense equipment, railway-related applications. *You can view the product catalog by downloading the PDF below.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

"MI-170 series" With RS-232C communication, measurement result output and setting data input/output can be performed. Up to 8 types of condition settings, such as upper and lower limit settings, can be configured. Pressure sensors can be selected from 4 types based on accuracy, gauge pressure, and differential pressure. The mounting size conforms to the DIN96 standard. By combining with the separate type air leak tester LPU-100 series, it can also be used as an air leak tester. "DG-960 series" Pressure sensors can be selected from 4 types based on accuracy, gauge pressure, and differential pressure. The mounting size conforms to the DIN96 standard. "MIZ-0175 series" A new multi-indicator that enhances the functionality of the versatile and high-performance conventional model "MI-170," improving operability and visibility through downsizing and the adoption of an LCD display. It allows a maximum sampling rate of 4000 times per second for stable measurements and is equipped with various correction functions and noise cancellation features, providing a wealth of functionalities.

● What is a flow meter? Flow meters measure flow rates using mass flow meters or laminar flow meters and perform pass/fail judgments based on flow rate criteria. They are ideal for measuring airflow and conducting performance tests. "FMZ-1063 series" This is a flow tester equipped with a mass flow meter. It offers high precision of ± 3.5 % of R.D. ± 1 digit (in the normal flow range). It features a time-saving function (scan measurement). The FMZ-1063 is a compact, all-in-one flow tester with various functions. "FU series" This is a flow measurement unit that integrates laminar and differential pressure sensors, making it smaller and lighter. When connected to a display indicator (model: MI-170), it can provide direct flow readings as well as pressure and flow judgments. "FLF-110 series" This is a laminar flow meter capable of measuring a wide range of flow rates from 2 NmL/min to 500 NL/min.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
