• 🔷 Measures on 2 Scales 🔷 Specific Gravity (D 20/20) and parts per thousand and replaces your poor quality and difficult to read hydrometer
• 🔷 Density Measurement Range 🔷 1.0-1.070, Minimum Scale is 0.001
• 🔷 Concentration Measurement Range 🔷 0-100‰, Minimum Scale is 1‰
• 🔷 ATC 🔷 Automatic Temperature Compensation, 0-10°C; ① It is necessary to keep the surrounding environment with sufficient brightness and a suitable temperature during use. There is no error when the temperature is 10-30℃. If it deviates from this temperature, there will be a certain error. ② Because people’s focal lengths are different, reverse rotation may be necessary when focusing
