    I know how to use hydrometers. I know to get the bubbles off before reading. This device is way off. Mine is reading way higher than my old hydrometer and my refractometer.

    The instructions say it has been calibrated at the factory. But when I fill it with fresh water it reads way over 1.000. The instructions also say to season the needle by soaking it in salt water. I’ve done that for three days and the needle hasn’t moved.

    I am certain my refractometer and old hydrometer are correct as they are both reading 1.024. If this new hydrometer were correct, at 1.03+, my fish would all be dead.

    On the plus side, this device is much easier to read than the older hydrometers. The use of the sponge on the intake to prevent bubbles is clever too.

    But this device is so inaccurate it’s useless.

    Needed to check saline in the shrimp tank. Easy to use and clean, have to set upside down on a flat surface to dry…. served purpose.

    I got like 20 opae ulas and they have to live in brackish water. I bought this to measure the level of salt i guess. you put the salt in water and just dunk the device in there to measure it. EASY
