Anderaa SeaGuard® RCM Series Single-Point Current Meter

Modular Design · Multi-Parameter Integration · Full Ocean Depth Coverage

A high-performance ocean observation system built on the proven SeaGuard data logger platform and advanced ZPulse Doppler technology. Available in first-generation (RCM) and second-generation (SeaGuardII RCM) models, it delivers high-accuracy current data through modern digital signal processing. Its modular smart sensor topology allows flexible integration of temperature, pressure, conductivity, dissolved oxygen, wave, and tide sensors. The SeaGuardII RCM is the world's only tow-tank-validated single-point current meter, offering industry-leading accuracy. Available in 300m, 3000m, 6000m, and optional 11,000m hadal versions, it suits environments from coastal seas to full ocean depth.
