Description
 
NIST calibrated reference hydrometers and thermohydrometers at the required Density/API test points (as specified by ASTM or the customer). At least three readings of the clients instrument (and at least six readings of the NIST reference standard) are taken at each test point. Readings are resolved under magnification to approximately one-tenth of the smallest scale division and are carefully noted. We report the mean of a minimum of three closely correlated readings
