Salinity Refractometer 0 ~ 100ppt 300011 - Sper Scientific

Salinity Refractometer 0 ~ 100ppt 300011 by Sper Scientific is a handheld refractometer specially designed for measuring salinity and specific gravity of seawater, aquaculture water, or other salt solutions. It features a compact and convenient design for easy use.

The device operates completely without power or batteries, using natural light to measure light refraction through the sample, delivering fast, accurate results with a clear scale showing two important parameters simultaneously.

With automatic temperature compensation (ATC) and simple calibration using distilled water, the 300011 salinity refractometer is suitable for both field and laboratory applications.

• Automatic temperature compensation (ATC), no manual temperature adjustment needed, ensuring stable and accurate measurements.
• Displays two parameters simultaneously: salinity (ppt) and specific gravity, convenient for users to monitor.
• Compact refractometer design, lightweight (86 g), easy to carry in a pocket.
• Completely battery-free operation, using natural light for measurement.
• Simple calibration with distilled water, can also calibrate with other standard solutions.
• Wide measurement range from 0 to 100 ppt salinity and specific gravity from 1.000 to 1.070, suitable for diverse applications.
• Rubber-coated frame for slip resistance and good insulation, minimizing hand temperature effects on results.
• Clear, easy-to-read scale, suitable for both beginners and experts.
