We have updated information about our new business ventures and initiatives.

Our company has developed a system that enables simple and highly accurate measurement of the calorific value of biogas, and we are conducting demonstration experiments for it.

By focusing on the methane gas contained in biogas and measuring its concentration, we can indirectly determine the calorific value. For measuring methane gas concentration, we use an infrared gas sensor that utilizes the infrared absorption wavelength of gas molecules. This allows for rapid and highly accurate measurement of gas concentration even in high concentration areas. It is equipped with a compact and inexpensive pressure reduction and flow rate stabilization system, enabling the extraction of process gas and real-time data acquisition. An example of methane concentration measurement data can be downloaded from the catalog. *For more details, please feel free to contact us. *Please note that we cannot reply to g-mail addresses on our company system.

Are you having trouble with "promoting carbon neutrality," "responding to the revised Energy Conservation Act," or "ESG management" for designated energy management factories?

Are you having trouble with "promoting carbon neutrality," "responding to energy conservation law amendments," or "ESG management"? In response to energy challenges in factories, such as reducing electricity consumption, decreasing fossil fuel use, and expanding the introduction of renewable energy, our company provides support from energy measurement to solutions based on our track record of 82 energy diagnostics (*). Since we can offer a one-stop solution from proposal to construction, we can promote carbon neutrality while keeping costs down. 【CO2 Reduction Benefits When Implemented (Partial)】 <Hotels> ■ CO2 Reduction Amount: 99t/year ■ Area of cedar forest that absorbs CO2 in one year: 11.6ha ■ Amount of wood pellets used: 162t/year (*) Energy diagnostic achievements…CO2 reduction potential diagnostic project (Ministry of the Environment) *For more details, please refer to the PDF document or feel free to contact us.

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.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

NDT Mart & Rental Co., Ltd. began selling its new electromagnetic ultrasonic thickness gauge, 'EMAT WIFI', on January 19, 2026. ◆ Electromagnetic Ultrasonic Thickness Gauge 'EMAT WIFI' The 'EMAT WIFI' is a thickness gauge that uses the electromagnetic ultrasonic (EMAT) method, which does not require a couplant (contact medium). Unlike conventional ultrasonic thickness gauges (UT), there is no need to apply a couplant; thickness measurements can be taken simply by placing the probe on the measurement target, making it ideal for beginners and screening in large-scale sites. It can measure materials with paint, scale, thick linings, and slight surface roughness, significantly reducing the hassle of pre-treatment. Additionally, it is equipped with WiFi communication capabilities, allowing for the confirmation and management of measurement data and waveforms in conjunction with smartphones and tablets. This facilitates smooth sharing of measurement results and data management on-site. It is optimal for measuring wall thickness and conducting corrosion inspections of plant equipment, piping, tanks, and steel structures. It contributes to the efficiency and reliability of thickness measurements in the field of non-destructive testing (NDT), such as maintenance inspections and equipment diagnostics.
