ASTM D1657 Density Or Relative Density Of Light Hydrocarbons

KN-1657A Pressure Hydrometer Cylinder Bath

Overview

KN-1657A Pressure Hydrometer Cylinder Bath conforms to the ASTM D1657 Standard Test Method for Density or Relative Density of Light Hydrocarbons by Pressure Hydrometer, is used for testing the density or relative density of light hydrocarbons including liquefied petroleum gases (LPG) having Reid vapor pressures exceeding 101.325kPa (14.696 psi). The apparatus is purged with a portion of the sample before filling with the portion to be used for testing. The pressure cylinder is filled to a level at which the enclosed hydrometer floats freely, and the cylinder is then placed in a constant-temperature bath. When the temperature has reached equilibrium, the hydrometer reading and the temperature of the sample are noted.

Features

1. The shell of the instrument is made of high-quality cold-rolled steel plate, and the surface is treated by electrostatic spraying and high temperature baking, which is easy to clean and corrosion-resistant

2. Imported fully enclosed compressor, equipped with self-protection function

3. If the temperature is too high, the system will alarms

4. High-power magnetic circulation system to ensure temperature uniformity

5. Ultra-thick plexiglass bath, transparent for easy observation

6. Microcomputer controller, PID function, digital display temperature (continuous display during test)

7. The cylinder is equipped with a thickened transparent protective cover to fully ensure the safety of the operator.
