Atago PEN-SW (W) Digital Pen-Style Salinity Refractometer

The Atago PEN-SW (W) is a high-precision digital handheld refractometer specifically engineered to measure the concentration of salt in water by weight (g/100g). Featuring an ergonomic pen-style design, this instrument is the perfect solution for quality control in brine preparation, food processing, and seafood management. Its unique "immersion" method allows users to dip the prism tip directly into the solution or touch it to a sample, providing instant digital readings without the need for manual sampling tools.

Built for versatility in industrial environments, the prism head of the PEN-SW (W) can withstand sample temperatures from 10°C to 100°C, making it suitable for testing hot liquids during the production process. The device includes Automatic Temperature Compensation (ATC) effective between 10°C and 40°C, ensuring laboratory-grade accuracy of ±0.2%. With an IP67-rated prism head (submersible) and an IP65-rated body, the Atago PEN-SW (W) combines industrial-grade durability with meticulous diagnostic speed, allowing for easy cleaning and maintenance under running water.
