The Handheld Salinity Refractometer (Model THE01502) is a precision optical instrument designed to measure the concentration of salt (NaCl) and specific gravity in liquids.

Ideal for aquariums, cooking, food processing, and laboratory use, it provides fast, accurate readings with minimal effort.

Its ergonomic rubber eyepiece ensures comfort, and the clear scale display allows direct reading for reliable salinity measurements every time.

Main Features:

• Wide Measuring Range: 0–100 ppt NaCl / 1.000–1.070 SG (0–10%)

• Accurate Results: Precision accuracy of ±1 ppt / 0.001 SG (±0.10%)

• User-Friendly: Simple to operate, calibrate, and read

• Comfortable Viewing: Soft rubber eyepiece for clear, strain-free readings

• Direct Reading Scale: Equipped with internal scale for easy observation

• Durable Case: Comes in a hard plastic storage box for protection and portability

• Multi-Purpose Use: Perfect for aquarium salinity testing, cooking, hydroponics, and general water quality checks

Operation:

1. Place a few drops of the sample liquid on the prism surface.

2. Close the prism cover and point the refractometer toward a strong light source.

3. Adjust the eyepiece for clear focus.

4. Read the salinity or specific gravity value directly from the internal scale.
