The CL-200A Dual-Channel Bipolar Temperature Controller from Warner Instruments is a versatile
and user-friendly thermal control device. This dual-channel automatic temperature controller is
capable of accurately maintaining two Peltier devices between -6°C and 65°C. The unit will also
maintain a resistive heater from ambient to 65°C.
While specifically designed for use with Warner’s Heating/Cooling Platforms and In-Line Solution
Heater/Coolers, this instrument can be easily adapted for use with custom-built equipment according
to the requirements of the user. When coupled with the SC-20 Dual In-line Solution Heater/Cooler,
the CL-200A provides efficient control of perfusion solution temperatures.
The unit is simple to use with a single control for temperature adjustment. Total automatic control is
provided in automatic mode, while manual control is available in manual mode. A loop-speed selector
is used to optimize the response of the system to accommodate thermal delay characteristics intrinsic
to the setup.
Features of the CL-200A include
Quiet operation suitable for use in sensitive electrophysiology applications
Automatic and manual modes
Single control temperature adjustment
Freeze alert
Built-in protection for Peltier devices
Selectable loop speed optimizes system speed and stability
Simultaneous monitoring of system temperature and a separate point of interest
Heat Loss compensation mode
Open thermistor fault protection
External inputs for computer control
Compatible with all Warner Peltier-driven Heater/Cooler devices
THIS EQUIPMENT IS NOT DESIGNED NOR INTENDED
FOR USE ON HUMAN SUBJECTS
