This Hydrometer Set consists of eight Specific Gravity / Relative Density (g/cm?) Plain Form Hydrometers for measuring specific gravity of heavy and light liquids in various ranges from 0.700 to 2.000. The 8 hydrometers included come in the following ranges: 0.700 to 0.810, 0800 to 0.910, 0.900 to 1.000, 1.000 to 1.220, 1.200 to 1.420, 1.400 to 1.620, 1.600, to 1.820, and 1.800 to 2.000. This kit also included one Total Immersion Thermometer to reference liquid temperature for accurate hydrometer readings.

Each hydrometer and the thermometer are 300 mm (12") long and are individually sterilized.
