Collection of large dead fish at aquaculture farms and sediment sampling at aquaculture sites using underwater drones.

We offer a "Sampling Kit for Underwater Drones" that can be tailored to the arms of your underwater drone. We design and manufacture large dead fish recovery kits, grab sediment kits, and core sediment kits utilizing the robotic arm of your underwater drone. Using underwater drones, we can safely and easily address challenges in aquaculture facilities and port facilities. 【Features】 <Large Dead Fish Recovery Kit> ■ Operate buoyancy devices with the robotic arm ■ Capable of recovering dead fish weighing up to 130 kg ■ We can suggest recovery kits based on the target fish *For more details, please download the PDF or feel free to contact us.

It is primarily designed for sampling with ROVs, but in coastal areas and lakes, sampling from the boat using diving or optional hand tools is also possible.

The "MW-MCS" is a sediment sampler that can collect surface sediments from the seabed or lakebed with minimal disturbance. The main body of the sampler consists of a sediment sampling head attached to a sampling tube. By gripping the handle of the sampling head with a manipulator or similar device, this product can be penetrated into the surface of the sediment for sampling. Additionally, there are two types of inner diameters for the sampling tube, and the lengths of the sampling tube and sampling tube holder can be modified according to your requirements. 【Features】 ■ Capable of collecting surface sediments from the seabed or lakebed with minimal disturbance ■ Removable rubber plug along with the bottom plate ■ Drilling processing is possible on the sampling tube *For more details, please refer to the PDF document or feel free to contact us.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

We have introduced Majesta Fragrance to a nightclub in Yokosuka City, Kanagawa Prefecture, creating a fragrant atmosphere throughout the floor. The model we have introduced is the "MF-02S," which costs 8,800 yen per month (tax included). The scent you have chosen this time is "Sabon," a high-quality soap fragrance reminiscent of luxury hotel amenities. Its clean and transparent refreshing scent spreads throughout the entire floor, warmly welcoming customers who visit. By introducing scent design to the nightclub, we can enhance the extraordinary experience and create a memorable space that lingers not only visually but also through "scent." Majesta Fragrance offers a rental service for commercial aroma diffusers, and we also provide a free trial installation. If you are interested in scent design, please feel free to contact us.

In the July 8, 2026 issue of Air Conditioning Times, we featured "Flex Chamber" and "SS Premier" in a duct special.

SS Premier has won an award at the 24th Environmental and Equipment Design Awards. This award is organized by the General Incorporated Association of Architectural Equipment Comprehensive Association and recognizes outstanding efforts in environmental and equipment design. We will continue to strive for further improvements in quality and technology.
