<b>[Product Information]</b><br>
<ul>
<li>DUAL SCALES - The measures on dual scales: Specific Gravity (0.001, Range: 1.000 - 1.070, D 20/20,) and Parts Per Thousand (1‰, Range: 0-100‰),working basis on that the liquid with different concentrations have different light refractive index.</li>
<li>HIGHLY ACCURATE WITH ATC - Automatic Temperature Compensation during 10 °C to 30 °C, eliminating data errors caused by temperature changes and guaranteeing a consistent accurate result.</li>
<li>DURABLE AND PORTABLE - The main part is made of chromium, it's light but durable.</li>
<li>EASY TO USE - Just need 2-3 drops of solution, you can get accurate readings.</li>
