Low-cost salt refractometer, 0 to 100 ppt salinity

Use these economical refractometers to take quick and easy measurements. Refractometers feature adjustable focus and a zero adjustment screw for calibration. Each refractometer is calibrated and adjusted to read at 68°>F (20°>C). Models with automatic temperature compensation (ATC) are ideal for applications where the temperatures of your samples vary. Refractometers are made of corrosion-resistant brass and have rubber-insulated grips. Include hard case, calibration screwdriver, and instructions. Shpg wt 1 lb (0.5 kg). Brix Refractometers measure soluble solid concentration of sugars, salts, proteins, and more in foods and liquids-ideal for quality control and R & D applications. Use to measure % Brix of juices,beverages, and other sugar-based liquids. Salt Refractometers measure salt content in parts per thousand (ppt) and specific gravity or % salinity, depending on model. Use to measure salt concentration of water or brine.
