hydrometer Set with thermometer & Measuring Cylinder - saltwater density for reef tanks, borosilicate 3.3 glass cylinder, measures and salinity,

Complete set for saltwater – The ARKA hydrometer set includes a hydrometer with integrated thermometer and a measuring cylinder made of borosilicate glass 3.3 to determine density and salinity in the saltwater aquarium. Hydrometer with thermometer – Density range 1.018 to 1.028 with a resolution of 0.0001, temperature 8 to 35 °C. Recommended range 1.022 to 1.024 at 25 °C, marked green on the scale. Measuring cylinder made of borosilicate glass 3.3 – The large vessel lets the hydrometer float freely for reading. Density values are recorded cleanly and in a controlled way, even with small water samples. High measuring accuracy – Made in France to strict quality standards in laboratory quality, maximum deviation +/- 0.0002 at 25 °C. For regular checks of sensitive saltwater parameters in the reef aquarium. Easy to use – Fill the water sample into the cylinder, insert the hydrometer so it floats freely and read at the waterline, preferably at 25 °C. Note the temperature deviation shown on the thermometer.
