Digital scale

Description

A digital scale that reads to 0.01 g weighs small amounts precisely. The most-rated one in our search, MAXUS's pocket scale, gives a maximum capacity of 200g and a readability of 0.01g, and its tare function lets you zero the weight of your container before weighing. It is sold for weighing herbs, powders, jewelry, and food, not for aquariums. No reference work in this catalog covers scales, so this page shows where aquatic work uses one. Merck's Veterinary Manual writes its salt treatments for fish by weight, in grams per litre: a salt solution of 3 to 5 g/L is recommended for transportation of freshwater fish, and permanently increasing salinity to 2 to 3 g/L in a freshwater system can minimize some parasitic protistans. Merck notes that salt is categorized as of low regulatory concern by the FDA, and that most species will tolerate the transport concentration for several hours or days. The treatment itself belongs on the aquarium salt page; it is repeated here only to show that the doses are given by weight. Laboratories that keep aquatic animals list the same instrument. A 2019 protocol for a disease challenge test in shrimp names a digital scale, precision 0.01 g, among its equipment. A 2025 zebrafish feeding study measured its fish the same way: all fish were deprived of food for 24 h, anesthetized with clove powder, and then weighed using a digital scale. None of these sources gives a dose for a particular tank, and this page does not work one out.
