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. Its 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 ppt (with 1 ppt scale divisions) and the other scale gauges Specific Gravity with a range of 1.**0 to 1.**0 (±0.**1 accuracy). Both enables the direct determination of salinity in water that contains dissolved salt and little or no other dissolved solids. It is suitable for a marine saltwater tank. It's FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading. It 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 *0pcs of 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, see Available Options below .
