The "PSD Displacement Measurement Device" is a non-contact, high-speed, high-precision static and dynamic displacement measurement device. It enables the measurement of static and dynamic two-dimensional displacements on a target's plane at long distances and wide fields of view, which could not be achieved with conventional laser or radar displacement meters. It can be applied to a wide range of measurements, including seismic diagnosis of architectural structures, maintenance and deterioration diagnosis of civil engineering structures, vibration monitoring, and displacement measurement during dynamic loading tests of piles. 【Features of the PSD Camera】 ■ Standard measurement distance of 100m ■ Wide field of view of 1000×1000mm (at a measurement distance of 100m) ■ High accuracy of 0.25mm (at a measurement distance of 100m) ■ Two-dimensional measurement (vertical and horizontal directions) ■ Standard for one target *For more details, please refer to the PDF materials or feel free to contact us.

The "ACT" is an acoustic concrete tester that uses sophisticated pulse-echo technology for measuring concrete thickness. It accurately measures the thickness of concrete structural components such as pavements, slabs, retaining walls, tunnel linings, and foundation footings. With this product, there is no need for adjustments to the input signal, measuring the wave propagation speed of the material, or drilling holes. 【Features】 ■ Accurately measures the thickness of concrete structural components ■ Capable of measuring the wave propagation speed of materials ■ Applicable for thicknesses from 75 to 900 mm ■ Easy-to-read display ■ Equipped with a battery that allows for a full day's work *For more details, please refer to the PDF document or feel free to contact us.

The "Home Pile Carry" is a foundation method that allows for easy construction in narrow spaces and indoors, thanks to its portable and disassemblable tower. The main body of the pile uses steel pipe piles that are excellent in seismic resistance and have stable quality. Its unique double wings penetrate the supporting layer reliably, demonstrating composite bearing capacity. Since it does not use cement milk or similar materials, there is no concern about groundwater contamination. Additionally, its low noise, low vibration, and completely non-discharging construction maintain harmony with the surrounding environment. 【Features】 - The main body of the pile uses steel pipe piles that are excellent in seismic resistance and have stable quality. - The unique double wings penetrate the supporting layer reliably, demonstrating composite bearing capacity. - No concern about groundwater contamination. - Low noise, low vibration, and completely non-discharging construction. - Maintains harmony with the surrounding environment. *For more details, please refer to the PDF materials or feel free to contact us.

The "PIT-X" is a pile integrity tester that is about the size of a palm and uses a wireless type accelerometer. There are no cables between the accelerometer and the main unit, and it retains all the functions that were present in the conventional "PIT-V." It also includes a fast Fourier transform function that is particularly useful for detecting relatively short pile lengths. 【Features】 ■ Size is about the size of a palm ■ Uses a wireless type accelerometer ■ No cables between the accelerometer and the main unit ■ All functions from the conventional PIT-V are inherited ■ Equipped with a fast Fourier transform function that helps in detecting relatively short pile lengths *For more details, please refer to the PDF document or feel free to contact us.
