2Intended use
JULABO circulators are laboratory devices which are designed for the
temperature control of certain liquid media in a bath tank or with a
refrigeration unit. The bath fluids recommended by JULABO must be
used as tempering media.
Units with pump connections allow the tempering tasks to be carried out
in an external temperature control system.
JULABO circulators are not designed for the direct temperature control of
foods, semi-luxury foods and tobacco, or pharmaceutical and medical
products.
•Direct temperature control means unprotected contact between the
object and the tempering medium (bath fluid).
•The devices are not suitable for use in potentially explosive
environments.

•These circulators are operated via the splash-proof keypad. The
microprocessor technology allows the setpoint to be set, displayed
and saved using the temperature display LED.
•The PID temperature control automatically adjusts the heat supply to
the requirements in the bath.
•ATC - Absolute Temperature Calibration (1-point calibration)
•The pump function can be switched from internal to external
circulation by a simple switchover button.
•Safety equipment to IEC 61010-2-010:
- Excess temperature protector is a safety device which is
independent of the control circuit whose value is set using a
tool (screwdriver).
