TECHNICAL NOTE 457
5. The Circle Heater has two temperature sensors, one internal and one external. The internal one controls the
heating of the Circle Heater. The external one, composed of a control box and a non-contact infrared sensor,
can monitor the temperature of the heated and mixed solution (see Figure 5). The Temperature Sensor Controller
can be easily attached to the Circle Heater by engaging the magnets that are inside the Controller and with the
ones in the side of the Heater. Just be careful to keep fingers away from the back of the Controller when doing
this as the magnets are strong and fingers can be pinched!
6. There are 2 holes for Temperature Sensor placement, use the one that works best for the pipetting head to be
used. The other one can be covered with the provided plug.
Figure 5. Attach the external Temperature Sensor Controller.
Figure 6. Position the external Temperature Sensor and take a reading by pushing the blue button.
