Milwaukee - MA887 Digital Seawater Refractometer
Overview
- Measures Salinity Using 3 Industry Standard Scales: PSU, PPT, & Specific Gravity
- Automatic Temperature Compensation for Consistent Readings
- Fast, Accurate Digital Results in Seconds
- Simple One-Button Calibration
- Ideal for Aquarists, Marine Biologists, & Aquaculture Professionals
The Milwaukee MA887 Digital Seawater Refractometer is a high-precision tool designed specifically for the needs of saltwater aquariums and marine applications. Unlike traditional refractometers that rely on manual interpretation, the MA887 delivers digital accuracy across three of the most widely used salinity measurement scales: PSU, PPT, and Specific Gravity (S.G.).
Whether you're maintaining a reef aquarium, studying ocean samples, or managing an aquaculture facility, the MA887 ensures dependable, fast results with minimal user effort. Automatic temperature compensation ensures your readings stay consistent regardless of ambient conditions.
3 Salinity Measurement Scales
- PSU (Practical Salinity Units): The modern standard in seawater salinity measurement, becoming the global benchmark for scientific and aquarium use.
- PPT (Parts Per Thousand): The legacy scale that expresses the amount of salt per thousand parts of solution.
- S.G. (Specific Gravity): The most common scale used with traditional hydrometers and analog refractometers.
Digital Accuracy & Easy Calibration
Calibrating the MA887 is as simple as pressing a button and using distilled water. Readings are displayed in seconds on the digital LCD screen, making the unit user-friendly and eliminating interpretation errors.
