【Instant inspection of bypass circuit】0.1[A] voltage measurement, voltage, BPD, and cluster integrated measurement, tester with voltage logging function【Demo unit available for loan】

This product can inspect the presence of open/short circuit failures in the bypass diodes within solar cell modules. Since measurements can be taken at the PV string level, such as in junction boxes, inspections can be conducted efficiently and safely without having to climb onto the roof. 【Commitment to Safety】 Measurements taken during the day can potentially damage solar cells, so our company has designed the product with safety in mind, allowing for short, high-speed measurements limited to low sunlight hours in the morning and evening, or at night. ■ High-speed measurement (approximately 1 second from measurement start to result display) ■ Capable of measuring and determining faults from a single module to the string level (supports strings up to 1000[V] / no voltage limit for nighttime measurements) ■ Two inspection modes: morning/evening mode and night mode for safe and reliable inspections ■ 0.1[A] voltage measurement selectable (breeder measurement) → confirmation of cluster faults ■ Bulk measurement mode for voltage, BPD, and clusters available ■ Equipped with tester function (voltage measurement) ■ Voltage logging function allows for measurement of ground-to-ground voltage → confirmation of safety * For details, please download the catalog or feel free to contact us. * Demo units are also available for loan, so please get in touch.

The "Mechanical Stitching 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 on 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.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
