Step-by-Step Usage Guide
-
Preparation
Before you start, gather the seawater sample you would like to measure. Make sure it’s at a temperature between 10 to 30 degrees Celsius for accurate readings. -
Calibration
While the ATC feature helps, it’s always good practice to calibrate your refractometer when moving from one environment to another. Input distilled water or a known standard and make any adjustments. -
Sample Measurement
Place a few drops of your seawater sample on the optical glass prism. Close the lid, ensuring that the sample spreads evenly. -
Reading the Scale
Look through the eyepiece, and you will see the illuminated scale. Read the measurements for both salinity and specific gravity. -
Cleaning
Always clean the prism with fresh water and a soft cloth after use. Proper maintenance ensures longevity and preserves accuracy.
Tips for Better Results
- Ensure proper lighting conditions when taking readings; too much glare can lead to misinterpretation.
- Regularly check for any air bubbles in your water sample on the prism, as they can skew results.
- Always keep your refractometer stored in a protective case when not in use to prevent damage.
