AUTOUTLET Salinity Refractometer for Aquarium Salinity Tester with ATC and Dual Scale 0-100 & 1.000-1.070 Specific Gravity Saltwater Tester for

In a recent review of the AUTOUTLET Refractometer, customers shared their experiences and inquiries about the product. The versatile 3-in-1 refractometer is designed for measuring animals' urine specific gravity and serum protein, and it comes with an automatic temperature compensation (ATC) function. Customers inquired about the calibration procedure, and it was clarified that manual calibration is required using distilled water, without a calibration certificate provided. There were some questions about using the tester for measuring salinity in drinking water and pool water, with mixed responses about its suitability for these purposes. Some users found success calibrating it with standard solutions, but there were uncertainties about calibrating it with RODI water, and the product was primarily recommended for testing seawater and reef aquariums. One customer question enquired about using the refractometer to measure salt in irrigation water, to which the response affirmed its usage for reef aquariums rather than irrigation purposes. Another inquiry sought clarity on the percentage scale reading, and it was explained that the percentage indicates salinity, representing the amount of dissolved salt substance per kilogram of water, with the salinity of seawater corresponding to 35‰. Overall, the AUTOUTLET Refractometer offers a convenient solution for animal urine-specific gravity and serum protein measurement with automatic temperature compensation. However, there are limitations and some uncertainties regarding its suitability for measuring salinity in drinking water, pool water, or irrigation water.
