For those seeking advanced technological solutions, the CMOS Seawater Refractometer presents an innovative alternative.
Refractometry is a technique that measures the extent to which light is bent, or refracted, when it moves through a substance. In the context of seawater analysis, refractometers determine the salinity by measuring the refractive index of the seawater sample. The refractive index changes with the concentration of dissolved salts, making it a reliable indicator of salinity levels. This method is favored for its simplicity and rapid results compared to chemical titration methods.
The Milwaukee MA887 is a digital refractometer specifically designed to measure the salinity of seawater. Unlike analog refractometers, the MA887 provides digital readings, enhancing accuracy and ease of use. It is equipped with an LED light source and a prism made of optical glass, ensuring precise measurement of the refractive index. The device displays results in various units, including Practical Salinity Units (PSU), Salinity in parts per thousand (‰), and Specific Gravity (S.G.). This versatility makes it suitable for a wide range of applications.
The Milwaukee MA887 boasts several features that set it apart from other refractometers:
With an accuracy of ±2 PSU, the MA887 ensures reliable data essential for scientific research and industrial applications. Its digital circuitry reduces human error associated with reading analog scales.

The Milwaukee MA887 serves a critical role in multiple sectors due to its accurate salinity measurements:
Understanding seawater salinity is vital in studying marine ecosystems. Salinity influences water density, circulation patterns, and the distribution of marine life. Researchers utilize the MA887 to monitor salinity changes that could impact biodiversity and ocean health.
In aquaculture, maintaining optimal salinity levels is crucial for the health and growth of aquatic organisms. The MA887 assists aquaculture professionals in regularly monitoring and adjusting salinity to create ideal breeding and farming conditions.
Environmental agencies use the refractometer to track salinity trends in coastal waters and estuaries. Changes in salinity can indicate pollution, freshwater influx, or climate change effects, making the MA887 a valuable tool for environmental assessments.
Educational institutions incorporate the MA887 into laboratory experiments and field studies, providing students with hands-on experience in marine science techniques. Its simplicity and accuracy make it ideal for educational purposes.
The Milwaukee MA887 offers several benefits compared to conventional salinity measurement techniques:
Traditional methods, such as titration, require multiple steps and reagents. The MA887 provides immediate readings, significantly reducing the time required for analysis.
Digital readings eliminate the subjective interpretation of analog scales. This precision minimizes errors and enhances the reliability of the data collected.
The MA887 requires only a small sample volume, allowing for more tests with limited resources. This feature is particularly beneficial in remote locations or when sample conservation is necessary.
By reducing the need for consumables like reagents and minimizing labor time, the MA887 proves to be a cost-effective solution in the long run.
Proper maintenance and calibration are essential to ensure the longevity and accuracy of the MA887:
The refractometer should be calibrated regularly using deionized or distilled water at 0 PSU. This practice ensures that the device provides accurate measurements over time.
After each use, the prism surface should be cleaned with a soft, damp cloth to prevent residue buildup, which can affect readings.
The MA887 is powered by a battery, and users should monitor the battery life indicator. Replacing the battery as needed prevents interruptions during critical measurements.
When not in use, the device should be stored in a clean, dry place. Extreme temperatures and humidity can affect its electronic components.
While the Milwaukee MA887 is a leading device in its category, understanding how it compares with other refractometers can guide users in making informed decisions:
Analog refractometers are generally less expensive but require careful interpretation of readings. Digital refractometers like the MA887 provide immediate, precise results, reducing user error.
