The "Air Permeability Testing Machine: Permatol" has been selected as a semi-recommended technology for the fiscal year 2021 by the Ministry of Land, Infrastructure, Transport and Tourism!

Completely non-destructive and very easy measurement of the air permeability of surface concrete! [NETIS Registration Number: QS-150029-VE]

The performance of concrete varies significantly depending on the concrete mix, placement method, type of formwork, and curing method. Therefore, verifying the quality of the surface concrete (cover concrete) is extremely important when considering durability performance. According to Swiss standard SIA 262:2003, "The impermeability of the cover concrete must be checked by permeability tests on cores taken from the structure or from the structure itself." Permatol AC+ can measure the air permeability of surface concrete completely non-destructively and very easily.

The air permeability of surface concrete can be easily measured completely non-destructively!

The permeability testing machine [Permatol AC+] can easily measure the permeability performance of surface concrete in a completely non-destructive manner. It adopts a two-chamber cell structure that is less affected by surrounding conditions, and the operation is user-friendly with a touch panel interface. It has various applications, including quality verification of cover concrete, effectiveness checks of surface modifiers and coatings, and verification of coating performance. It is also registered as a NETIS technology (Registration Number: QS-150029-VE).

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence.

This motor is designed with measures to eliminate such ignition sources. 【Available stock models】 ■ Pressure-resistant explosion-proof motors, explosion-proof grade d2G4 - Foot-mounted type, output 0.4 to 3.7 kW, 4 poles - Flange type, output 0.4 to 0.75 kW, 4 poles ■ Increased safety explosion-proof motors, explosion-proof grade eG3 - Foot-mounted type, output 0.2 to 0.75 kW, 2 and 4 poles - Flange type, output 0.2 to 0.75 kW, 2 and 4 poles

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
