## 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 CelsiusATC - automatic temperature compensation (compensation range 0 30 Celsius) focus possibility length 195 mm quality technical design Content and equipment a firm plastic case a refractometer a cleaning cloth 3 suction tube a screw driver a operating instructions.

Review: I’ve been using the Agriculture Solutions Salinity Refractometer for my saltwater fish tank, and it has made maintaining proper salinity levels incredibly easy. Accurate salt levels are critical for marine fish and corals, and this refractometer gives consistent, reliable readings every time. The 0–100 PPT range is perfect for seawater and marine aquarium use, and the automatic temperature compensation (ATC) is a huge plus. I don’t have to worry about room temperature affecting the results, which gives me peace of mind that my readings are accurate. Calibration was straightforward, and the results are easy to read and interpret, even for someone who isn’t a professional. Compared to test strips or swing-arm hydrometers, this refractometer is far more precise and dependable. It’s helped me keep my salt levels stable, which has made a noticeable difference in the overall health and behavior of my fish. If you maintain a saltwater aquarium and want a simple, accurate, and reliable tool for monitoring salinity, this refractometer is absolutely worth it. It takes the guesswork out of marine tank maintenance and makes routine checks quick and stress-free.

## Questions & Answers

**Q: Is this any use for hydroponics?**
A: It is used for testing the salt water fish tank.

**Q: I want to test the brackish canal water to see if i can use it for irrigation. will this tester work?   I was told to check the salinity of the canal**
A: Yes, brackish water ranges between 0. 05 to 30 PPT

**Q: What does this come with**
A: All you get is the refractometer, case and a small screwdriver for adjusting it.  Unless they have added something since we bought ours about a year ago. It will not let me post a picture or I would.

**Q: Hi, i bought a calibrating fluid and calibrated my refractometer to sg 1.026 but when i test it on distilled water it reads 1.010. why is that?**
A: According to R Homes Farleys article this is because this refractometer was made to measure pure salt solutions and they don’t have the exact reflective index of sea water that has some additional elements.  Therefore calibrating with a solution that matches the reflectivity of seawater at 35ppt is needed and once done it will not measure distilled or Rodi water accurately. But you will have a more accurate measurement for your salt water aquarium.
