Connect to a solar cell and operates at the maximum operating point (Pmax). It can track the maximum power point under various solar illumination, angle, and temperature conditions.

To evaluate the power generation performance of solar cells, it is necessary to actually put the solar cells in a generating state. Without connecting a load, no current will flow, and thus power generation performance cannot be measured. This device consumes the output power by converting it into heat internally when the solar cells are connected. By simply establishing a minimal measurement environment, it is possible to measure the power generation of the solar cells (the device measures voltage, current, and power every second). For tracking the maximum power point, a unique MPPT tracking method is employed, which, in addition to the conventional sequential power comparison (hill climbing method), sweeps the I-V curve output characteristics of the solar cells once per minute to explore the maximum operating point, thereby performing MPPT control. As a result, even when the maximum operating point (Pmax) changes significantly due to sudden weather changes or shading, it continues to track the maximum operating point. Additionally, when combined with a PV analyzer (I-V curve tracer), it is possible to construct a simulated system under load for outdoor exposure tests. This device is used for applications such as confirming domestic power generation amounts for new types of solar cells (perovskite type), vehicle-mounted solar cells, and OEM products.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

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.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

● 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.
