ASTM Hydrometers 82H through 125H
Our hydrometers are produced in the United States by outstanding
manufacturers known for quality craftsmanship and accuracy of reading.
Manufactured strictly in accordance with all applicable ASTM specifications,
these ASTM hydrometers have become the industry standard for close,
accurate readings. All instruments in this series are available
with our NIST Traceable certification, and as such serve as primary
reference standards in many governmental and private laboratories.
ASTM API Thermo-Hydrometers
These hydrometers are fabricated with a thermometer in the lower
body for convenience to the user. For any particular API gravity
range, three temperature ranges are available, coded as follows:
L=Low 0/150F, M=Medium 30/180F, H=High 60/220F. The units listed
below are the most popular. Variations are available on special
request.
ASTM API Specific Gravity Series Hydrometers
Specific gravity @ 60/60F (relative density) hydrometers as specified
in ASTM E-100
ASTM API Thermo-Hydrometers With Thermometer In Stem
The 30/220F thermometer with the scale in the stem is useful for
testing of heavy oils where dark color prevents reading the thermometer
in the body of a conventional thermo-hydrometer.
