Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium 0-100 PPT with Automatic Temperature Compensation

Top-Notch Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium 0-100 PPT with Automatic Temperature Compensation

Recommended for these features->

✅ Measures salt water or salinity of water
✅ Features automatic temperature compensation
✅ Comes with hard case, dropper, screwdriver, user manual and cleaning cloth
✅ The main part is made of chromium, it’s very durableCheck Price

1. Measures salt water or salinity of water- A Salinity Refractometer is a tool used to measure the salinity of water. The device consists of an optical chamber, which holds samples and provides light for refraction measurements, and a prism that bends the light into two beams traveling at different angles. One beam travels through air (refracted) by the sample; one beam travels directly from air to glass or liquid (transmitted). At each point in between, there will be interference colors produced from wave fronts bouncing off surfaces within both beams as they overlap near their focal points on opposite sides of this plane. This system allows users with limited experience working with optics to quickly interpret results.

2. Features automatic temperature compensation- A salinity refractometer is an instrument used to measure the salt concentration in seawater or aquarium water. The Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium 0-100 PPT with Automatic Temperature Compensation automatically compensates for temperature changes. It has a range of 6 to 100 parts per thousand (ppt) with automatic compensation from 10 degrees celsius up to 40 degrees celsius, giving you accurate measurements anywhere between these temperatures

3. Comes with hard case, dropper, screwdriver, user manual and cleaning cloth- If you’re looking for a reliable way to get your salt water or freshwater system’s salinity level, the Salinity Refractometer is perfect. It comes with everything you need in one neat kit: an automatic temperature compensation device, 3 interchangeable lenses and a hard case that keeps all the parts safe from scratches. In addition, it has a dropper and screwdriver included so there are no excuses not to use this handy tool!

4. The main part is made of chromium, it’s very durable- A refractometer is a tool that measures how much light is bent when it passes through different substances. This one, in particular, has an automatic temperature compensation feature and can be used to measure salinity levels from 0-100 PPT with accuracy. The Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium 0-100 PPT with Automatic Temperature Compensation comes included with instructions on how to use the device as well as what type of readings you should expect at each level
