- 6-
1 Introduction
The K259XX Constant Temperature Bath is
mechanically refrigerated to provide sub-ambient
temperature measurements using a pressure
hydrometer cylinder. The water bath is capable of
immersing two pressure hydrometer cylinders at
60°F (15°C) for density and relative density
determinations of LPG and other light hydrocarbons.
This manual provides important information
regarding safety, technical reference, installation
requirements, operating condition specifications,
user facility resource requirements, and operating
instructions for the K259XX Constant Temperature
Water Bath. This manual should also be used in
conjunction with applicable published laboratory
procedures. Information on these procedures is
given in section 1.2.
