The scale of salinity meter provides a direct reading of the specific gravity and concentration (part per thousand) of salt in water. Made by experienced craftsmen and it is unlikely to break down! Keep the important information about water in your mind Check the important units of refractometer aquarium. 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. Versatile applicable The refractometer salinity 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. The vivid and sharp reticle chart is for easy and comfortable reading. Packages contains: 1 x Salinity refractometer 1 x Dropper 1 x Wipe cloth 1 x Mini screwdriver 1 x Protective carrying case 1 x Operations manual ## Features - Proof your water quality quickly and reliable. The professional refractometer is ideal for aquarium, seafood water tank, salty pools, spas and many others. Heavy-duty and lightweight with its aluminum construction. Cushioned with soft & comfortable non-slip rubberized grip handle. Measures on 2 scales, Specific Gravity (D 20/20) and parts per thousand (‰) to provide a direct and clear reading. The automatic temperature compensation (ATC) is capable of measuring with high accuracy and provides high precise results. Comes with protective carrying case, salinity refractometer, dropper, screwdriver and cleaning cloth. ## Images ![ETvalley Hydrometer Dual Scale Salinity Refractometer for NaCl Level (0-100ppt) and Specific Gravity (1.000-1.070) in Aquarium, Sea Water and Salt Water with Automatic Temperature Compensation - Image 1](https://m.media-amazon.com/images/I/71Mdksad6EL.jpg) ![ETvalley Hydrometer Dual Scale Salinity Refractometer for NaCl Level (0-100ppt) and Specific Gravity (1.000-1.070) in Aquarium, Sea Water and Salt Water with Automatic Temperature Compensation - Image 2](https://m.media-amazon.com/images/I/61iw-F907aL.jpg) ![ETvalley Hydrometer Dual Scale Salinity Refractometer for NaCl Level (0-100ppt) and Specific Gravity (1.000-1.070) in Aquarium, Sea Water and Salt Water with Automatic Temperature Compensation - Image 3](https://m.media-amazon.com/images/I/61KcXVMsxsL.jpg) ![ETvalley Hydrometer Dual Scale Salinity Refractometer for NaCl Level (0-100ppt) and Specific Gravity (1.000-1.070) in Aquarium, Sea Water and Salt Water with Automatic Temperature Compensation - Image 4](https://m.media-amazon.com/images/I/716FBioxBJL.jpg) ![ETvalley Hydrometer Dual Scale Salinity Refractometer for NaCl Level (0-100ppt) and Specific Gravity (1.000-1.070) in Aquarium, Sea Water and Salt Water with Automatic Temperature Compensation - Image 5](https://m.media-amazon.com/images/I/61NeXyjk3ZL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use and good price *by W***D on Reviewed in the United States on September 28, 2017* This works well for us.
