Even in an anaerobic environment, detectors that can "visualize hydrogen" can be combined with a multi-channel synchronous measurement system to enable the confirmation of hydrogen gas behavior/distribution in space, supporting the establishment of a safe hydrogen leak detection system. The visualization of hydrogen gas in the target space allows for the numerical confirmation of leaked hydrogen, aiding in the optimal design and shape verification of enclosures. It is also used to verify the installation positions of commercially available hydrogen sensors. By feeding back measured data into CDF and other formats, even more accurate analyses can be achieved. The advanced research institute ISAS/JAXA has adopted our hydrogen visualization system in the development of next-generation rocket hydrogen engines.

○ Intrinsically safe explosion-proof design that does not use electricity ○ Selective reaction only to hydrogen at 1000 ppm ○ Usable in an oxygen-free, reduced pressure environment ○ Easy connection to commercially available recorders (data loggers) ○ Easy integration as a hydrogen probe into existing equipment + modular use

In order to eliminate the trade-offs of gas sensors, we have developed a sensor module for "hydrogen leak detection" that is highly sensitive and has excellent hydrogen selectivity. 【Features】Hybrid Sensor Module (Trigger Sensor + Main Sensor = Hybrid Sensor Module) <Ultrasonic Hydrogen Gas Sensor (Trigger Sensor)> ■ High sensitivity (1,000 ppm) ■ High-speed continuous detection (captures instantaneous hydrogen) ■ Capable of detecting other gas concentrations as well <Alloy Thin Film Sensor (Main Sensor)> ■ Thin film of hydrogen-absorbing alloy that reacts only to hydrogen ■ Reacts exclusively to hydrogen even in mixed gas environments ■ Detects hydrogen even in an oxygen-free environment *For more details, please refer to the PDF document or feel free to contact us.

Our company is collaborating with the Shikoku Research Institute to develop a wearable device called "Hydrogen Flame Visualization Smart Glasses" to visualize colorless and transparent hydrogen flames. This device allows for efficient fire inspections and various research activities hands-free, and it is designed to confirm the presence, location, and scale of hydrogen flames to enable rapid firefighting activities. It is a product that contributes to improving the safety of facilities handling hydrogen and aids in research on hydrogen power generation and heating furnaces. 【Specifications of the "Hydrogen Flame AR Smart Glasses"】*Test model for demonstration evaluation Frame rate: 10fps or higher Storage: 16GB External dimensions: 135×96×55mm Weight: 190g Power supply: USB-C DC5V *For more details, please refer to the materials available for download in PDF format.

The "Multi-Point Hydrogen Leakage Monitoring Network System" is a system designed to safely operate the supply of odorless hydrogen through pipelines, demonstrated in the hydrogen pipeline of Kitakyushu City. Wireless hydrogen sensors are installed in handholes. By combining these with a "leakage hydrogen guidance cover," early leakage detection is achieved. In the operation of odorless hydrogen, there is no need for the costs of odorization and deodorization. This contributes to a hydrogen supply chain built on a maintenance system that does not rely on human intervention. 【Components (Excerpt)】 ■ Wireless, battery-operated IoT hydrogen sensors ■ Fiber optic hydrogen sensors ■ LPWA cloud network ■ Leakage hydrogen guidance cover *For more details, please download the PDF or feel free to contact us.

Maintenance-free: Wireless hydrogen sensor Unmanned & labor-saving: LPWA cloud network Rapid hydrogen leak detection: Leak hydrogen induction cover Inspection port: Hand holes, etc. We propose a maintenance sensor system that has proven experience in Kitakyushu City's hydrogen town and hydrogen pipelines, which can be implemented for the safe operation of hydrogen pipelines between industrial parks and coastal areas.
