Hanna Instruments - Powder Reagents for Iron Checker (HI 721), 25 tests

Powder reagents for Phosphate Checker (HI 713), 25 tests.

Ref: HI713-25

Liquid reagent for seawater alkalinity (HI 755), 25 tests.

Salimeter from Aqua Medic is used for the simple determination of the salt concentration in saltwater aquariums . In saltwater aquariums the specific gravity should be between 1.022 and 1.025.

35 ppm calibration solution for refractometer.

The Aquarium Systems hydrometer allows you to accurately measure the density of seawater at a lower cost.

The seawater refractometer offers exceptional accuracy because it uses a specific algorithm developed to measure the absolute salinity of seawater at a temperature of 25°C.
