Rosette Sampling System(Multi-Parameter Water Sampler)
Product Overview
Frankstar Rosette Sampling System is a reliable, CTD-compatible water sampler built for programmable, depth-resolved seawater sampling. Featuring high-precision electromagnetic induction release technology, the system supports flexible user-defined sampling triggers based on depth, temperature, salinity, and scheduled time.
Engineered for maintenance-free operation and superior structural durability, the rosette system delivers stable and repeatable sampling results across complex aquatic environments, including coastal zones, estuaries, and open oceans. Fully customizable configurations of bottle quantity, sampling volume, and pressure rating make it suitable for versatile oceanographic research and long-term marine environmental monitoring.
Key Features
- Multi-Parameter Programmable SamplingSupports fully automated sampling triggered by real-time depth, temperature, salinity, or preset time schedules, enabling high-precision layered seawater collection.
- Maintenance-Free & Corrosion-Resistant DesignAdopts premium anti-corrosion materials and contact-free electromagnetic driving structure. Only simple rinsing is required after field deployment, greatly reducing daily maintenance workload.
- Compact & High-Reliability StructureCircular rosette layout optimizes spatial structure for compact installation. The integrated electromagnetic release mechanism ensures stable mechanical performance during long-term underwater operation.
- Fully Configurable Sampling BottlesFlexible configurations with 4, 6, 8, 12, 24, or 36 sampling bottles. Bottle volume and pressure resistance levels can be customized to match different survey depths and experimental standards.
- Wide CTD CompatibilityFully compatible with mainstream CTD sensors on the market, realizing synchronous data acquisition and water sample collection for integrated ocean observation.
