Description

This handheld salinity refractometer operates on the principle of light refraction through a liquid sample to determine its salinity concentration and specific gravity. The integrated Automatic Temperature Compensation (ATC) mechanism corrects for ambient temperature variations, ensuring measurement accuracy without manual adjustment. The device is engineered for durability with a lightweight aluminum housing and a non-slip rubber grip, making it suitable for frequent use in marine, aquaculture, and laboratory environments.

Designed for straightforward operation, a small sample is placed on the main prism using the included pipette. The user then views the scale through the eyepiece to obtain an immediate reading. The unit can be recalibrated with distilled water and the provided tool, maintaining long-term measurement integrity. Its compact form factor and protective carrying case facilitate easy transport and storage for on-site testing needs.

Key Features

  • High-precision optical refractometer for salinity and specific gravity measurement.
  • Automatic Temperature Compensation (ATC) for accurate readings across 10°C to 30°C.
  • Robust aluminum alloy body with a superior-quality rubberized grip.
  • Clear, magnified eyepiece with a well-defined dual scale (0-100% salinity / 1.000-1.070 sg).
  • Simple calibration process using distilled water and the included mini-screwdriver.
  • Optimized for portability with a compact design and protective carrying case.
  • High-value build quality suitable for professional and educational use.

Applications

  • Marine aquarium and reef tank salinity monitoring.
  • Aquaculture and hydroponics system water quality management.
  • Field testing of seawater salinity for marine biology and oceanography.
  • Water treatment plant and desalination process monitoring.
  • Educational use in chemistry and environmental science labs.

Frequently Asked Questions

How do I calibrate this handheld refractometer?

Calibration is performed using distilled or deionized water. Place a few drops of water on the main prism, close the cover plate, and look through the eyepiece. Use the included mini-screwdriver to adjust the calibration screw until the scale reads exactly 0% salinity or 1.000 specific gravity. The device should be recalibrated periodically for optimal accuracy.

What is Automatic Temperature Compensation (ATC) and how does it work?

ATC is a built-in mechanism that automatically corrects the refractive index reading based on the ambient temperature, typically within a range of 10°C to 30°C (50°F to 86°F). This eliminates measurement errors caused by temperature fluctuations, ensuring you get accurate salinity and specific gravity values without needing to consult temperature correction charts or perform manual adjustments.

What is the difference between measuring salinity and specific gravity?

Salinity measures the total concentration of dissolved salts in water, expressed as a percentage (%). Specific gravity is a dimensionless ratio comparing the density of the water sample to the density of pure water. This refractometer provides both measurements on a single, dual scale. They are correlated parameters commonly used in marine and aquarium keeping to assess water quality.

What kind of maintenance does this refractometer require?

Maintenance is minimal. After each use, gently wipe the prism and cover plate with a soft, damp cloth to remove the sample. Avoid using abrasive materials or solvents that could scratch the optical surface. Store the device in the included protective case to prevent dust accumulation and physical damage. Regular calibration with distilled water is recommended to maintain accuracy.
