K26150 Pressure Hydrometer Cylinder


Test Method
Density and relative density measurements of light hydrocarbons, including Liquified Petroleum Gas (LPG), are used for transportation, storage and regulatory purposes. The measurement is made by floating a thermohydrometer in a sample that has been introduced into a pressure cylinder.

Features and Benefits
• Conforms to ASTM D1657 and related specifications

• Built-in safety relief valve


K26150 Pressure Hydrometer Cylinder
Transparent plastic cylinder mounted between machined aluminum end plates and surrounded by stainless steel safety guard. Use together with ASTM 310H Thermohydrometer to determine density or relative density of LPG and light hydrocarbons. Equipped with inlet, outlet and vapor vent valves for admitting sample and purging cylinder. End plates have positive sealing buna-N O-rings and are joined by sturdy steel support rods. Top plate detaches easily without tools for insertion or removal of thermo-hydrometer. Safety relief valve prevents unsafe pressure build-up inside cylinder. Mounted on a finished steel base.

Conforms to the specifications of: ASTM D1657; GPA 2140; IP 235; ISO 3993

Safety relief valve: 200psi (1.4MPa)
