Capturing the reality of damage caused by wildlife with a camera. We meet your expectations for long-term unmanned filming in aquaculture and seaweed bed sites.

The "MW-UWC-01" is an underwater time-lapse camera that can be used for monitoring food damage. It has a waterproof performance equivalent to a depth of 50 meters, allowing for long-term fixed-point shooting. It is equipped with a built-in battery and memory, enabling standalone use. The camera can continuously shoot for up to 13 months (with a shooting interval of 10 minutes), and the shooting interval can be set freely from 1 to 99 minutes, depending on the scene you are using it for. Additionally, a file transfer function can be added as an option. 【Features】 ■ Low power consumption ■ Automatic shooting stop ■ Time-lapse settings *For more details, please download the PDF or feel free to contact us.

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

We offer a "Sampling Kit for Underwater Drones" that can be customized to fit the arms of your underwater drone. We design and manufacture large dead fish retrieval kits, grab sediment kits, and core sediment kits that utilize the robotic arm of your underwater drone. By using underwater drones, you can safely and easily address challenges in aquaculture facilities and port facilities. 【Features】 <Large Dead Fish Retrieval Kit> ■ Operates buoyancy devices with the robotic arm ■ Capable of retrieving dead fish weighing up to 130 kg ■ We can suggest retrieval 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 sampling head attached to a sampling tube. The grip part of the sampling head is held by a manipulator or similar device, allowing the product to penetrate 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 adjusted 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.

On September 11, 2025, AC Tasarim, a cable blade manufacturer, and our company signed a sales agency agreement for Japan. This was also announced in the company's press release and on social media. Founded in Turkey in 2003, AC Tasarim manufactures flexible EMI cable shields (copper braid), polyester braid, meta-aramid braid (Nomex cable sleeves), flat copper braid busbars/ground braids, all AA59569-coded copper braids, and released AeroBraid in 2025, the world's lightest EMI braid. All manufactured copper braids are certified to military standards. AC Tasarim products hold key certifications including VDE/VG certification, German Federal Armed Forces certification, NATO NSN coding, AS9100 quality certification, and JOSCAR certification. Cable braids and EMI shielding products, essential for wire harnesses in the aerospace and defense industries, are becoming increasingly difficult to source as demand rises. TC Tasarim products are stocked by manufacturers and distributors to ensure quick response times.

The "CCS2" is a ceiling-mounted vehicle counting sensor that employs an infrared reflection method. It can detect vehicles in both directions with just one unit, accurately counting vehicles even during traffic jams or when vehicles pass each other. Additionally, this product can be used not only for vehicle counting but also as a sensor for departure warnings. Furthermore, by using a separately sold dedicated remote control, it is easy to reset the sensor alone, switch the counting direction, and change the patterns of the departure warning timer. 【Features】 ■ Angle adjustment is possible up to ±5° ■ Can be installed in locations with high ceilings up to 4m ■ Detection area consists of 40 spots, allowing for wide-range detection ■ The display LEDs are color-coded by direction, making operation confirmation easy.

Many people may have questions like, "What can be done with IoT?" and "What is needed?" upon hearing the term IoT. Through digital communication, it is possible to obtain various information such as flow sensors, valves, circuit boards, and abnormal monitoring that were not accessible with traditional analog control. For example, by monitoring the valve opening, one can detect blockages in the equipment and identify leaks from cumulative flow. This information directly contributes to reducing downtime and improving quality through continuous long-term monitoring and knowledge-based management. Compatible models include those with digital communication via RS485, in addition to traditional analog controls like 0-5VDC and 4-20mA. (Older models such as the 58xxS, MfxxS series, SLA58xxS, and SLAMfxxS series). Even older models that do not support digital communication can be upgraded to the latest mass flow models, enabling digital communication. The dimensions between new and old models are the same, and no wiring changes are necessary. Additionally, we can provide control boxes for data collection from mass flow. This enables a "visualization" of small IoT without making large changes to the equipment.
