  Flow meter (flow tester, flow unit, laminar flow meter)(0)

  Flow rates are measured using mass flow meters and laminar flow meters, and quality assessments are conducted based on flow rate criteria. This is ideal for measuring air flow rates and performance testing.

• 

  Air leak tester(0)

  The "air leak tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence or absence of leaks based on pressure changes. When a leak-free master and a workpiece with a leak are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence or absence of a leak is 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 measuring medium, it incurs no running costs and is environmentally friendly.

• 

  Hydrogen leak detector(0)

  This tester can measure leaks even in small areas that could not be measured in an air leak test, and it can also identify the leak locations. It uses a hydrogen 5% + nitrogen 95% industrial mixed gas (non-flammable gas: ISO 10156:2017) as a tracer gas.

• 

  Helium leak test system(0)

  This is a leak test system suitable for high precision or high-pressure leak testing. The helium leak test system uses helium gas as the detection gas (tracer gas) and is a test system that detects leaked helium. Among Fukuda leak testers, it is the leak test method capable of detecting the smallest leaks.

• 

  Dedicated leak test system for small electronic components(0)

  This is a device for conducting leak tests on small electronic components that require airtightness, such as crystal devices, ceramic oscillators, optical devices, power semiconductors, CAN devices, laser diodes, MEMS devices, SAW filters, small relays, and capacitors. Leak tests for sealed products need to be conducted in two types: gross leak tests and fine leak tests. We offer fully automatic machines that can perform the entire process in one unit, as well as dedicated machines (custom-made) and convenient tabletop types for sampling inspections.

• 

  Ultra Fine Leak Test System(0)

  MEMS components and small electronic parts, such as angular velocity sensors and infrared image sensors, need to maintain airtightness inside the product over a long period of time, requiring high gas tightness. Fukuda has developed a high-sensitivity helium leak detection technology called the "capsule accumulation method" as a measurement technique for ultra-micro leaks. The MUH-0100 series is a gas tightness inspection device specifically designed for ultra-micro leak measurement using the "capsule accumulation method."

• 

  Sealed product air leak test device(0)

  This is an air leak test device that inspects the airtightness, sealing properties, and waterproofness of electrical equipment, packaging containers (cosmetics, food), and more. It checks for leaks in products such as smartphones, tablet devices, keyless switches, wristwatches, bottle containers, and cosmetic containers (eyeliner, mascara).

• 

  Packaging Container Air Leak Test Device(0)

  This is a leak testing device that identifies any peeling or tearing of packaging containers for pharmaceuticals, as well as the presence of pinholes, and conducts container closure integrity testing (CCIT). It can be applied to a wide variety of packaging containers, including soft packaging, bottle containers, and glass containers, starting with pharmaceutical packaging. The measurement method employs the <sealed chamber method (pressure change leak testing method 1)>. By placing the sample in the chamber and applying pressure or vacuum, quantitative testing is performed by measuring the pressure changes within the chamber. It can be used in various situations such as manufacturing offline, manufacturing inline, CMC laboratories, quality control laboratories, and stability testing. *The containers subject to inspection are referred to as "work" or "sample." Here, specific samples are referred to as "samples" to differentiate the terminology.

• 

  Pseudo-defect / pinhole(0)

  This is a pseudo-defect (reference test piece) with specified hole diameter and hole length. It can be used in pressure change leakage testing and liquid immersion testing. It can be utilized for standard setting and validity evaluation using positive controls (defective product samples). ● Evaluation of packaging integrity in accordance with JP18 ● Setting of "maximum allowable leakage limit" ● Testing for the intrusion of water vapor, oxygen, and microorganisms ● Quantification from qualitative testing methods (standard leakage specifications converted to hole diameter)

• 

  Flow standard / reference instrument / calibrator(0)

  It is used for daily inspections, sensitivity checks, and measuring work volume of leak testers.

• 

  Peripheral devices (leak test, leak tester)(0)

  By improving the usage environment of the leak tester with peripheral devices, its performance and durability can be enhanced.

• 

  Electric Air Regulator(0)

  This is a self-developed electro-pneumatic regulator with a control reproducibility of ±0.1%. It offers a wide range of products from low flow to high flow.

• 

  Regulator(0)

  Please use this to adjust the test pressure for the leak test. By supplying a stable test pressure, more accurate measurements can be achieved.

• 

  Digital pressure gauge(0)

  This is a digital pressure gauge equipped with a high-precision pressure sensor developed in-house.
