In the process of underwater photography, low illumination is often encountered, especially as the water depth increases and the distance from the water surface increases, the light becomes darker. Sometimes, due to the turbidity of the water, the lighting is poor. What kind of underwater camera is better to use in this low light underwater situation?It is recommended to use the deep-sea ultra-low light high-definition camera independently developed and produced by Shanghai Weihai Marine Technology Co., Ltd. Shanghai Weihai Marine Technology Co., Ltd. has launched multiple deep-sea low light high-definition cameras for low illumination underwater environments, among which,SWT-IPSC-1KDZ (LI) deep-sea ultra-low light high-definition cameraSuitable for working in water depths of 0-6000 meters, with a titanium alloy shell, it can meet 1080P high-definition camer...

Ice stained sediment refers to the stones and debris transported and accumulated by glaciers. Collecting complete annual sediment particles under the ice is beneficial for analyzing the seasonal changes in biological flux and corresponding biogeochemical patterns in the central Arctic Ocean from a global change perspective. The ocean plays a very important role in regulating global climate change, as it can clearly record the flux and composition of particulate matter deposited in the ocean.And the equipment for collecting such ice stains and sediments has to mention sediment traps. A sediment trap is a sampling device that is deployed on the seabed for a long time to collect sediment particles. It is an instrument used to continuously collect sediment particles in water bodies and can obtain sediment input flux and seasonal variability. Sediment traps usually come in different ...

The underwater LED lights developed by Shanghai Weihai Marine Technology Co., Ltd. are mainly used for deep-sea lighting, suitable for water depths of 0-6000 meters, with two power options of 100W and 300W, adjustable or non adjustable.The 300W underwater lighting lamp adopts a high-voltage wide range power supply design, mainly considering that the ROV system can easily obtain high voltage by rectifying the underwater power supply through a transformer. Currently, the voltage is generally around 120VDC, and this LED lamp is designed for a wide range input of 75-200VDC, which can be applied to various high-power underwater work platforms and has stronger adaptability to power supply. The luminous wick adopts a COB structure independently designed and produced by SMT, with a high comprehensive luminous efficiency of 95-115lumens/1W. Due to the compact u...

Deep sea miniature low light standard definition analog camera, model: SWT-AVSC-D1FP (M800).

With the continuous deepening of people's development and utilization of marine biological resources, seabed mineral resources, and marine energy, the number of seabed environmental monitoring instruments and engineering application instruments deployed to the seabed is gradually increasing, and the recycling of marine equipment is also of paramount importance. In this way, an underwater acoustic release device has emerged.The underwater acoustic release device is mainly used for automatic recovery of underwater equipment. It sends remote release instructions through the deck unit, and the response release device receives the command and verifies it. After the verification is correct, the release mechanism is opened and disconnected from the gravity anchor. The response release device and equipment float out of the water surface under buoyancy, and then recover.This device mainly ...
