Atago MASTER-S/Mill α (Alpha)

The Atago MASTER-S/Mill α (Alpha) is a high-performance handheld refractometer specifically engineered to measure the salinity and specific gravity of seawater with meticulous accuracy. This professional instrument displays salinity in parts per mille (‰) and features a dual-scale for monitoring specific gravity simultaneously. Constructed with a new generation of corrosion-resistant materials, the MASTER-S/Mill α is built to withstand the harsh, abrasive nature of salty samples, making it an essential tool for aquaculture, marine biology, and professional aquarium management.

Equipped with Automatic Temperature Compensation (ATC), the device ensures precise readings regardless of ambient temperature fluctuations between 10°C and 30°C. Its robust IP65 rated water-resistant housing allows for easy cleaning under running water and safe operation in humid environments. The ergonomic, streamlined telescope-style grip and the innovative spoon-shaped tip for smooth sampling enhance user efficiency during field tests. The Atago MASTER-S/Mill α represents the gold standard in seawater analysis, combining rugged durability with laboratory-grade optical precision.
