Featuring automatic temperature compensation (0-30°C) and dual scales for specific gravity and salt concentration, it delivers fast, reliable readings using just a few drops of water. Packaged with essential accessories in a durable case, it’s the go-to tool for marine enthusiasts and researchers seeking accuracy and ease of use. ## Description Refractometer for seawater and marine fishkeeping aquarium 0-100 ppt Details : This optical refractometer (salinity meter) has scales in the range of 0 - 100 ppt(0 - 10 %). The reading resolution is 1 ppt. It is designed for the measurement of seawater (marine aquaria) or very low concentrated salt solutions. The second scale is for reading of the salt solution density in range 1.000 to 1.070 g/cm3 (resolution 0.001 g/cm3). The usual salinity of the selected aqueous solutions 1.Fresh water --- 50 ppt (Salinity 36 ppt means, that there are 36 grams of salt in 1 liter aqueous solution.) Measurement: The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale. General technical parameters reference temperature 20 Celsius ATC - automatic temperature compensation (compensation range 0 ~ 30 Celsius) focus possibility length ~ 195 mm quality technical design Content and equipment 1x firm plastic case 1x refractometer 1x cleaning cloth 1x suction tube 1x screw driver 1x operating instructions Review: easy to use and accurate - I recently got the RGBS Salinity Refractometer for testing seawater and salt solutions, and I have to say, I'm really impressed! Right out of the box, it feels well-made and sturdy, which was a pleasant surprise. Using it is pretty straightforward. The maker included clear instructions, which helped me set it up without any fuss. All I had to do was place a few drops of the seawater on the prism and look through the lens to get the reading. The scale is easy to read, and I was able to take measurements quickly. It felt like a science experiment without being complicated, which is right up my alley. One thing I particularly appreciated was how accurate the readings appeared to be. I compared it with a few other sources, and it seemed spot on! As someone who enjoys marine life and occasionally considers saltwater aquariums, it gives me peace of mind knowing I can keep track of salinity properly. In terms of maintenance, it's also quite easy to clean—just a quick rinse after use, and it’s good to go. Overall, if you're into marine biology, aquarium keeping, or just want to measure salinity for any salty solution, I think the RGBS Salinity Refractometer is a solid investment. It’s simple, effective, and provides the accuracy you’d hope for.
