The first scale is used to measure the salt content in water and is mainly used in marine aquariums.
The second scale shows the specific gravity, i.e. the density ratio (kg/l at 20 °C) between pure water and the liquid being tested (usually salt water). The specific gravity can also be used to determine the salt concentration, among other things.
| Scale | Measurement Range | Resolution |
| Salt content | 0-100‰ | 1‰ |
| Specific Gravity | 1,000-1,070 | 0,005 |
| Weight | 0,3 kg |
|---|---|
| Dimensions | 210 × 60 × 90 cm |
| Automatic Temperature Compensation | Yes |
Scope of delivery
The refractometer is supplied as standard in a gray box with a foam insert
