General Description
The Stuart SCT1 temperature controller is the
ideal instrument for the accurate temperature
control of aqueous and oil based samples in the
laboratory. The SCT1 can be used in two
different modes; as a precise temperature
controller from 20 to 200°C or as a digital
thermometer from -4 to 325°C. With digital
setting and display of temperature, the SCT1
temperature controller is accurate to ±0.5°C.
The SCT1 is compatible with the following Stuart
hotplates and hotplate stirrers: US150, US152,
US152D, UC150, UC152, UC152D, SC162, and
CC162.
Safety Advice before use
If the equipment is not used in the
manner described in this manual and
with accessories other than those
recommended by Stuart the protection
provided might be impaired.
This equipment is designed to operate under the
following conditions: -
❖ For indoor use only
❖ Use in a well ventilated area
❖ Ambient temperature range +5°C to +40°C
❖ Altitude to 2000m
❖ Relative humidity not exceeding 80%
❖ Use with a minimum distance all around of
200mm from walls or other items.
❖ Never move or carry the unit when in use or
connected to the hotplate.
❖ Do not use in a hazardous atmospheres or
with hazardous materials
Preparation for use
To use the SCT1 temperature controller with
either a metal top or ceramic top hotplate, place
the hotplate on a firm, level surface.
Open the jaws of the retort clamp on the rear of
the SCT1 temperature controller by turning the
clamp knob anticlockwise. The clamp can be
used with retort rods from 9.5mm to 13mm
diameter. Slide the SCT1 on to the retort rod and
tighten by turning the clamp knob clockwise.
NB: DO NOT OVER TIGHTEN
Connect the SCT1 controller plug to the DIN
probe socket at the rear of the hotplate (Figures
1 and 4).
Connect the probe plug to the probe socket at
the rear of the controller (Figures 2 and 4). To
ensure the best connection, tighten the locking
collar on the plug by turning clockwise.
Connect the mains supply lead to the IEC socket
at the rear of the hotplate and switch on at the
mains. Where the unit has a mains on/off switch,
switch the unit on using this switch.
To switch on the SCT1 temperature controller,
turn the heat control knob on the hotplate
clockwise (Figure 3).
NB: The controller power is supplied by the
hotplate
The SCT1 temperature controller and hotplate are
now ready for use. Correct communication
between the SCT1 temperature controller and
the hotplate is indicated by the illuminated amber
contact thermometer indicator on the front panel
of the hotplate.
NB.: The hotplate and controller will
perform an automatic self-test at switch
on, before the current temperature of the
probe is displayed. The factory default set
temperature is 20°C.
