KELVIN provides traceable calibration of all types of density devices, including density hydrometers, alcohol hydrometers, ASTM hydrometers, specific gravity hydrometers and more.

We use Cuckow’s method (NIST 250-78r1), a primary method that leads to smaller uncertainty than the comparison method.

 Calibration Scope:

Hydrometer: 0.600 g/m³ to 1.8 g/m³  

Alcoholmeter: 0 to 100% v/v
