For precise, fast measurements of the salt content/density and temperature in all saltwater aquariums. Take note of the areas marked in green (recommended range) of the integrated measuring scale.

For precise measurements, the ARKA aerometer should be used in a large vessel, floating and at a recommended temperature of 25°C.

We recommend our special ARKA measuring cylinder made of borosilicate glass 3.3 in laboratory quality.
