Density Standards

Density Standards

Specifications: Weighted, hermetically sealed, amber glass capsules; 1/4" (6.4 mm) OD, 3/4" (19 mm) long, slightly longer for higher densities; permanently marked for identification; precisely calibrated at 23°C (73.4°F) unless otherwise specified.

Application: Sink-Floats are usually selected to meet specific density liquid monitoring or individual liquid density requirements by ordering singly, in pairs, or in series by Catalog No.

Data Sheet

Purchase orders must specify the exact density and tolerance. If this information is omitted, the widest tolerance will be supplied.

Application: Sink-Float Screening Sets are available in series commonly used in making quick estimates of densities.

The precise density of a Sink Float Standard within a set may not end in a “0” or a “5”. However, its precise density will be clearly marked and calibrated within the chosen tolerance (i.e. A nominal 1.00 gm/cc Standard for Set #13550 will be marked with its density within its tolerance so its density will be a number between .995 and 1.005 and marked as to its actual density).

Standard Temperature: Calibration will be at 23°C unless another temperature is specified. See below.

Temperature Adjustment Charge: For other than 23°C Use CAT # 13200; $158.75 (For each combination density-temperature specification in a single order)
