Made in
accordance with API specifications and calibrated to API scale Modulus
141.5 at 60 degrees F. All hydrometers are of precision grade. The
hydrometers are constructed with a solid alloy ballast and designed
to permit quick penetration to the settling point, creating no air
bubbles. Scale is sealed in place by a red glass strap fused to the
stem and the top of the gravity scale even with the last number line.
Certified
Hydrometer
Certified hydrometers are available upon request. Hydrometers are
certified at three points on the hydrometer scale as specified by
NIST (formerly NBS. On the combined form, the thermometer is provided
with a 60 degree F test point correction. Each instrument is accompanied
by a document of certification that includes the correction of each
point tested.
