boxtech Aquarium Marine Test Sea Saltwater Hydrometer Reef Ocean Hydrometer Salinity Meter for Pool Aquarium Water Salinity Specific Gravity Test

Introduction

Clearly Safe Zone IndicatedIncludes solinity and specific grovity scales.The outside rang of scale indicates salinity(PPT).The inside range of scale indicates gravity.And with safe zone clearly indicated.Range of use: 0-40 degrees (1.000-1.030).If the salinity ppt between 32 – 40,show that the salinity hydrometer is high If the salinity ppt between 27 – 31,show that the salinity hydrometer is normal If the salinity ppt between 0 – 26,show that the salinity hydrometer is light. Easy to Read and UseThe easy-to-read swing-arm pointer and extra wide stable base provide an accurate test result. Wide UsageFit for brackish and marine aquariums.Perfect for testing both salinity and specific gravity of your brackish and marine tank.Includes solinity and specific grovity scales.Suitable for fresh water and sea water. Durable Clear AcrylicAccurate, durable, and easy to read your marine aquarium’s salt level and specific gravity,Small and waterproof.if the specific gravity between 1.000 – 1.019,show that the specific gravity is small if the specific gravity between 1.020 – 1.023,show that the specific gravity is nomal if the specific gravity between 1.024 – 1.030,show that the specific gravity is big. Safe MaterialMade of plastic,aquarium clear Automatic Accurate Readable SaltWater Hydrometer.
