The MTC-20/2SD temperature control system is designed for heating purposes in electrophysiological experiments. The MTC-20/2SD system is housed in small desktop cabinet that can be placed close to the microscope, with built-in power supply and cooling elements for the power devices. The system guarantees low noise operation and has special protection features to prevent the preparation from damage.
The MTC-20/2SD incorporates two electronic thermometers for small semiconductor sensors (R2252, i.e. the sensor has a resistance of 2252 Ω at 25 °C), two digital temperature displays (XX.X °C), a set-point control with digital readout (XX.X °C), a PI (proportional-integral) controller with adjustable parameters, an output power control unit and a high-power output stage (DC, continuous operation) for resistive ( i.e. heat only) loads with electronic protection circuits. The power output is short circuit protected, the output power is limited electronically. Maximal output voltage is approximately 12 V, the current is limited to 1 A.
The MTC-20/2SD controller is delivered with a power cord and a user manual. Sensors must be purchased separately.
