About this item
- The Salinity Tester is better than traditional hydrometers and cheaper than digital refractometer; ① It is necessary to keep the surrounding environment with sufficient brightness and a suitable temperature during use. There is no error when the temperature is 10-30℃. If it deviates from this temperature, there will be a certain error. ② Because people’s focal lengths are different, reverse rotation may be necessary when focusing
- The Salinity Refractometer has dual scale. The scale range of this refractometer is salinity of 0~100‰ (1‰=1PPT=1000PPM, PPT means “parts per thousand”, PPM means “parts per million”). It also shows the corresponding specific gravity range from 1.000 to 1.070.
- Easy to carry and use, no batteries required. Just 2-3 drops of solution and a few seconds, you'll get accurate readings. Under the guidance of the user manual, you'll learn how to easily calibrate and use the refractometer.
- With ATC function, the refractometer is equipped with automatic temperature compensation part inside, which minimizes the effect of the temperature.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
