Hygger Aquarium Hydrometer - Multi - Multi | 12.8cm | HG-047

Tests salinity and specific gravity in marine aquariums to help maintain a healthy tank. Key Features: 1. Included: 1x Hydrometer, • 1x Stick, • 1x Base 2. An accurate and reliable aquarium salinity test equipment. 3. Delivers precise full-range salinity and specific gravity readings 4. Includes a built-in base so you can rest the hydrometer on a countertop or other flat surfaces when taking salt readings 5. Salinity tester fits brackish and marine aquariums 6. The hydrometer supplies an optimal specific gravity/salinity range indicator PPT scale with an extra-wide stabilizer base 7. A bubble diffuser on water intake prevents micro-bubbles from forming on the needle 8. Easy to fill and convenient without wetting your hands 9. Perfect for testing both salinity and specific gravity of your brackish and marine tank 10. Suitable for fresh water and seawater 11. The salinity tester is made of transparent acrylic material, which is relatively hard and easy to read 12. Easy to read and use 13. Simply dunk it in the aquarium to fill it with water, then put it on a level surface to read the scale 14. Easy-to-read swing-arm pointer and extra wide stable base provide an accurate test result 15. The reading is temperature-corrected and accurate to +/-0.001. The unit of specific gravity is 1. 000-1. 030 (ppt value: 0-43.9 degrees), the safe area is 1.020-1.023 (ppt value: 30.2-34.2 degrees), and the low specific gravity area is 1.000-1.019 (ppt value: 0- 28.9 degrees), the higher specific gravity area is 1.024-1.030 (ppt value: 35.5-43.9 degrees) 16. The proportion of range: 1.000-1.030 17. Salinity range: 0-43.9 18. Size: 8.5 x 12.8 x 1cm 19. Colour: Multi 20. Material: Acrylic 21. Made in: China 22. Dimensions (HxWxD): 23.5x19x2 cm 23.
