QYSEA FIFISH Water Sampling Tools Turn your FIFISH ROV into a full underwater research platform. The QYSEA FIFISH Water Sampling Tools are a suite of purpose-built payloads designed for water quality monitoring, environmental sampling, and subsea data collection — giving researchers, scientists, and inspection professionals the ability to gather precise measurements and physical samples directly from the ROV. Each tool mounts directly to compatible FIFISH ROVs and is engineered for reliable performance at depth. Select the tool that fits your mission — from physical water and sediment collection to real-time dissolved oxygen, salinity, turbidity, and pH sensing. Note: Please allow 3–8 weeks for delivery. Available Tools Water Sampler (100ml) — $1,500100ml collection capacity, 150m sampling depth. Collect water samples from a wide range of underwater environments. Water Sampler (500ml) — $1,800500ml collection capacity, 150m sampling depth. Ideal for larger-volume water collection needs. Dissolved Oxygen Sensor — $7,500Monitor and record dissolved oxygen levels in real time for aquatic health and environmental assessments. Salinity Sensor — $5,000Measure dissolved salt concentration in water — essential for marine and estuarine research. Turbidity Sensor — $6,000Quantify suspended solids by measuring light scattering in the water column. pH Sensor — $4,500Measure water acidity and alkalinity for environmental monitoring and water quality analysis. Mud Sampler — $1,680Retrieve and sample underwater sediments and seabed materials for geological and environmental study. Multi Water Quality Sensor — $19,999All-in-one sensor for comprehensive, simultaneous water quality monitoring across multiple parameters. Compatibility QYSEA FIFISH ROV series (compatible models)
