1. INTRODUCTION
1.1. The Cole-Parmer CN-200D Digital Controller provides a convenient means of
temperature control, using microprocessor techniques to give ease of operation and
good accuracy. It can be used either in ON/OFF mode with the hysteresis loop
controlling power switching or it can be used as a PID (Proportional, Integrated,
Derivative) controller. Alternatively it may be used simply as a temperature
measuring device.
1.2. Temperature sensing is performed by a plug-in platinum resistance probe. The
sample temperature is displayed on the LED display. This product is suitable for
bench and retort stand mounting or wall mounting using the bracket and screws
provided.
1.3. The CN-200D has a short mains output lead with an IEC socket to connect it to the
resistive load. An accessory extension mains lead is available where remote
operation is required (e.g. in a fume extraction unit).
1.4. The CN-200D controller must be used in conjunction with a suitable heating or
cooling device e.g. mantle, electric Bunsen or hotplate. For cooling applications
please contact your distributor / suppler or contact Antylia Scientific at the address in
section 11. Customer Support.
