PERFORMANCE DATA
The following table identifies the specifications for
the Circulating Baths.
INSTALLATION
WARNING
INSTALLATION SHOULD BE COMPLETED BY
QUALIFIED PERSONNEL ONLY.
Location -
The most uniform operating conditions
will be obtained by placing the bath on a level
surface in an area remote from drafts, ventilating
outlets, radiators, and other rapidly changing
ambient conditions.
Electrical Connections -
IMPORTANT
For personal safety, this apparatus must
be properly grounded.
GENERAL INFORMATION
Precision Circulating Baths are widely used in
research and quality control. Their superb
temperature uniformity and stability makes them
especially desirable for legal or reference tests.
The microprocessor control panel houses all
functions necessary to operate the bath. The 5
push-button switches and single digital display
window allow the operator to adjust bath
temperature and temperature calibration via a single
set of controls.
The proportional integral temperature control
coupled with agitation supplied by a centrifugal
pump located in the control housing allows precise
temperature control. Use of the gable cover
provided is required to maintain optimal temperature
sensitivity.
A high limit thermostat is provided and can be set
to prevent heater runaway in the event of
temperature control failure.
The interior of the bath is constructed of stainless
steel and is designed for operation with distilled
water or water solutions, such as water /ethylene
glycol with corrosion inhabitants added. The body
is made from galvanized steel and is painted for
added protection. A drain is located at the far left
hand end of the bath. A stainless steel gable cover
is also provided with the bath.
The 230-volt units are identical in appearance to
the 115-volt units.
