Features:

• Salinity refractometer is designed for testing the concentration of salt water and brine and used for quality control in research and clinical laboratories and marine industry
• Scale provides a direct reading of the specific gravity and concentration (part per thousand) of salt in water
• One scale checks the NaCl levels with the range of 0-100 ppt (with 1 ppt scale divisions) and the other scale gauges
• Specific gravity with a range of 1.000 to 1.070 (±0.001 accuracy)
• Both enables the direct determination of salinity in water that contains dissolved salt and little or no other dissolved solids
• Suitable for a marine saltwater tank
• Fully equippedwith ATC that automatically adjust itself to correct temperature discrepancies during use
• Capable of measuring with high accuracy and provides precise results
• Equipped with vivid and sharp reticle chart for easy and comfortable reading
• Uses ambient light only and no batteries are needed
• Made by experienced craftsmen and are unlikely to break down
• Plus an option to get an extra 50-pieceof transfer pipettes in 1mL and/or 3mL, a bottle of dioptic oil (calibration oil) and a reference block just by adding a small amount to your order
