【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
