Product Description
The Yulgary series of salinity refractometers, including models YG1507, YG1508, YG1509, and YG1510, offer advanced measurement capabilities for those in need of precise salinity and specific gravity assessments. Designed with Automatic Temperature Compensation (ATC), these refractometers ensure accuracy over a range of environmental conditions, making them ideal for both field and laboratory settings.
Built from durable pure aluminum, these refractometers are designed to withstand the rigors of frequent use while providing stability and longevity. The YG1507 model measures salinity from 2-4% (20-40 ppt) with specific gravity ranging from 1.015 to 1.030 sg. The YG1508 extends the salinity range from 0-4% (0-40 ppt) while maintaining the same specific gravity range. For those requiring broader measurement capabilities, the YG1509 supports a salinity range of 0-10% (0-100 ppt) with a specific gravity up to 1.070 sg. The YG1510 model is ideal for high-salinity solutions with a range of up to 28% salinity.

Frequently Asked Questions
What is the purpose of Automatic Temperature Compensation (ATC)?
ATC ensures that the refractometer provides accurate readings despite changes in temperature, which can affect the density of the solution being measured.
How do I calibrate my Yulgary refractometer?
To calibrate, adjust the calibration screw with a screwdriver while using distilled water to standardize the device to 1.000 specific gravity at room temperature.
Advantages and Disadvantages
The primary advantage of Yulgary salinity refractometers is their accuracy and ease of use, even for novices. The built-in ATC minimizes the errors that temperature changes could introduce in the measurements. They also feature robust construction, crafted entirely from pure aluminum, which ensures their durability over time.
However, a potential disadvantage might be the initial need for calibration to maintain accuracy, especially if the device is frequently subjected to varying temperatures. Additionally, some users might find the wider scale of salinity in certain models less necessary for their specific applications.
Field Use of the Product
The Yulgary salinity refractometers are prized in fieldwork for marine biologists, aquarium hobbyists, and laboratory technicians due to their portability and precision. In practical use, they allow the user to determine the salinity of water samples quickly, which is crucial for maintaining the right balance in aquariums or for conducting field research on water bodies.
In the field, the refractometers can measure directly from the sample source, with the ATC feature compensating for temperature fluctuations, ensuring that readings are reliable and quick, a vital need when conducting time-sensitive marine research.
Recommendations
To maximize the utility of your Yulgary refractometer, regularly clean the prism and cover plate with a soft, lint-free cloth to prevent any residual buildup that could affect the readings. Always recalibrate the device after significant environmental changes to maintain its precision. When using the refractometer for critical tasks, consider taking multiple readings to confirm accuracy.
Lastly, store your refractometer in a cool, dry place to protect it from moisture and without exposure to harsh chemicals, which could potentially corrode the aluminum structure over time.
