Product Description
Pressure Hydrometer Cylinder ASTM D1657 and ISO 3993
Pressure Hydrometer Cylinder is conforming to SH/T 0221 anf ASTM D1657 and ISO 3993(Standard Test Method for Density or Relative Density of Light Hydrocarbons by Pressure Hydrometer).
It is applicable at test temperature, Density of LPG and light hydrocarbon which vapor pressure are less than 1.4 Mpa can be tested using this Hydrometer.
Made of plexiglass(plastic), valves, etc, Both ends are sealed tightly with metal and neoprene gaskets. Conforming to the design and recommended dimensions given in below drawing. The cylinder is of such dimensions that the hydrometer float freely within it.
Warning: A protective shield shall be placed around the cylinder. Replace any cylinders that show signs of fogging, crazing, cracking, or etching.
