The Hikari Accuprobe Hydrometer is a top - notch tool for marine aquarium enthusiasts. It's a highly precise and user - friendly specific gravity meter with a wide measurement range. Unlike other quick - dip hydrometers, it gets rid of common inaccuracy problems. It can take water samples from a 6 - inch depth, away from surface influences, giving you a more accurate 'true' water sample. This hydrometer features a durable build for long - term use. The 'Dry Hands' design prevents contamination of the aquarium water. It measures specific gravity and salinity (PPT) with an accuracy of ±0.001. It has an auto - temperature - correcting function for warm water aquariums between 68°F to 85°F (20°C to 30°C). You can take readings either inside or outside the aquarium. The self - leveling, hanging device helps collect perfect samples, and its scientifically verified design offers ultimate accuracy. Before first use, fill it with aquarium saltwater and let it sit on a level surface for 24 hours to season the measurement needle. To use, submerge it about 6 inches to the water level line. When the water reaches the fill line, remove it and place on a level surface for an accurate reading. Avoid air bubbles on the pointer; tap gently to remove them if needed. Read specific gravity on the inside scale and salinity in PPT on the outside scale. A specific gravity of 1.020 to 1.023 is ideal for most marine aquariums. Rinse with fresh water after each use. If salt deposits build up, soak in lukewarm water or vinegar for 30 minutes, rinse, air - dry, and rinse again with warm fresh water before next use. Each hydrometer has an individual certified calibration number for the most accurate readings.
Hey there! Using the Hikari Accuprobe Hydrometer is a breeze. First, before using it for the first time, fill it with saltwater from your aquarium and let it sit on a flat surface for 24 hours. This helps get the most accurate readings later. When you're ready to use it, submerge the hydrometer about 6 inches into the water until it reaches the water level line. Wait for the water to reach the fill line, then take it out and put it on a level surface. Make sure there are no air bubbles on the pointer. If there are, just tap the hydrometer gently to get rid of them. You can read the specific gravity on the inside scale and the salinity in parts per thousand (PPT) on the outside scale. For most marine aquariums, a specific gravity between 1.020 and 1.023 is great. After you're done using it, always rinse it with fresh water to keep it accurate. Sometimes, salt deposits might build up on the pointer. If that happens, soak the hydrometer in lukewarm water or vinegar for 30 minutes, rinse it with fresh water, let it air - dry, and then rinse it again with warm fresh water before using it next time. Each hydrometer has its own calibration number, so you know it's been carefully tuned for accurate readings.
