Salinity Refractometer 0~100 PPT

We have been developing and selling this series of instruments for about 10 years, with a very professional team and factory. Our focus has been on supplying constant, stable, high-standard products to customers all over the world.

Product Overview

Our products are equipped with high-quality optics and smooth focusing. The main body is made of aluminum alloy, and the internal optical lens with a high refractive index makes up the precision optical system. The instrument is resistant to abrasion and corrosion, allowing it to measure the salinity of general corrosive liquids. However, we do not recommend measuring these liquids for an extended period, and any residue should be cleaned immediately after measurement.

Features

This salinity refractometer has several key features that make it an ideal tool for various applications. These include:

• Dual Scale: Measures both Specific Gravity and PPT, allowing you to get results in two different units at the same time with just one test.
• ATC Function: Equipped with an automatic temperature compensation function, which minimizes the impact of temperature on accuracy.
• Include: Comes with a hard case, droppers, a screwdriver, a user manual, and a cleaning cloth, providing everything you need to get started.

Scale Range

The scale range of this refractometer is 0~100‰ (1‰=1 PPT=1000PPM), and it also shows the corresponding specific gravity range of 1.000 to 1.070. These are the most common units for showing salinity of water, and with this refractometer, you can get results in two different ways at the same time with just one test. The minimum reading resolution is 1 ‰, making it possible to measure low-concentrated salt solutions.

Intended Uses

This salinity refractometer is ideal for various applications, including:

• Marine Monitoring: Perfect for simple marine monitoring and research, as most seas have a salinity between 30‰~35‰.
• Aquariums Water Monitoring: Ideal for aquariums or marine fishkeeping amateurs, as it helps maintain the salinity of water similar to sea water.
• Swimming Pool Water Measuring: Useful for measuring the salinity of pool water, especially when using a salt chlorine machine, with a recommended salinity range of 3‰~7‰.
• Lab or Industry Purposes: Suitable for lab and industry use for testing salinity solutions in the range of 0~100‰.

Pros and Cons

Pros:

• Easy to use, with a simple calibration and measurement process.
• No battery required, making it a convenient and portable tool.
• Automatic temperature compensation for accurate results.
• Dual scale for measuring both Specific Gravity and PPT.
• Includes a hard case, droppers, screwdriver, user manual, and cleaning cloth.

Cons:

• May not be suitable for measuring highly corrosive liquids for an extended period.
• Requires immediate cleaning of any residue after measurement.

Conclusion

This salinity refractometer is a reliable and accurate tool for measuring the salinity of water in various applications, including marine monitoring, aquariums, swimming pools, and lab or industry use. With its easy-to-use interface, automatic temperature compensation, and dual scale, it is an ideal choice for anyone looking for a high-quality refractometer.
