Precison ASTM-like combined form hydrometers made to meet ASTM and API specifications, which incorporate a thermometer in the hydrometer

The temperature standardization is 60/60F. The hydrometer scale division are 2.0 degrees. The hydrometers will perform with the same accuracy as the ASTM hydrometers with mercury thermometers.

The thermometer is made with a non-mercury, blue spirit, has a range of 30 to 180 degrees farenheit and is mounted in the body of the hydrometer. Length of hydrometer is 380mm.

Used to measure the density according to API degree scale for petroleum applications.
