Controlling Solution
Temperature Using External
Probe
To control the solution temperature plug a PT100 probe
into the probe receptacle located on the back side of
the unit. Place the probe into the solution. The display
will indicate the actual temperature of the solution as
measured by the probe.
The external probe offers more exact temperature
control than regulating the top plate by the internal
sensor. If you need to maintain a precise setpoint it
is recommend to use a probe to control the solution
temperature instead of controlling by the top plate
temperature.
When using a probe with the Cimarec
recommended that a clamp on a support rod be used to
hold the probe in the solution.
To ensure accurate probe readings, as much of the
probe sheath as possible should be immersed in the
solution. Make sure the probe is immersed in the liquid
and is not located in air or outside of the solution. If the
probe is plugged into the hot plate, but is not in solution
while the heat control is operating, the temperature
display will continue to indicate an ambient temperature,
and a probe out of solution error will occur. Because
the set point cannot be reached the heating element
will continue to supply heat to the top plate, and the
maximum top plate temperature(300°C, 400°C or
540°C) may be reached. If the remote probe does not
sense a temperature change in three minutes the unit
will display ExProbe Err and shut down.

Heating Small Volumes

Preheating small volumes is not necessary as it may
cause the temperature to overshoot the desired set-
point.
Heating Metal Vessels and
Sand Baths
Cimarec + is capable of precisely regulating the top
plate temperature, metal vessels and sand baths may
be heated safely without the danger of the ceramic top
breaking. Use the lowest temperature setting possible
for applications to limit thermal stress to the ceramic top.
Using a metal vessel or sand bath may reduce the life of
the stirring hot plate.
