Semetall Salinity Tester Transparent Acrylic Aquarium Sea Hydrometer

• 【SPECIFICATION】The reading is temperature-corrected and accurate to +/-0.001. The unit of specific gravity is 1. 000-1. 030 (ppt value: 0-40 degrees), the safe area is 1.020-1.023 (ppt value: 27-31 degrees), and the low specific gravity area is 1.000-1.019 (ppt value: 0- 26 degrees), the higher specific gravity area is 1.024-1.030 (ppt value: 32-40 degrees)(Note: PPT value indicates salinity in the outer range of the scale)
• 【MATERIAL】The salinity tester is made of transparent acrylic material, which is relatively hard and easy to read the salt and specific gravity of your marine aquarium
• 【 DESIGN 】 The easy-to-read swing arm pointer and ultra-wide stable base provide accurate test results
• 【APPLICATION】The aquarium saltwater hydrometer can perfectly test the salinity and specific gravity of brackish water and marine fish tanks, including the solubility and specific gravity scale. At the same time, it is very suitable for fresh water and sea water
• 【NOTE】Before using the salinity hydrometer tester for the first time, fill it with warm water and wash it with detergent before using it. After use, immerse the salt water meter in weak acid (vinegar) for 30 minutes, rinse with tap water and air dry
