npi electronic MTC-20/2S Temperature Control System

The MTC-20/2S temperature control system is designed for heating purposes in electrophysiological experiments.

The MTC-20/2S 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

Set-up

The MTC-20/2S incorporates two electronic thermometers for small semiconductor sensors (R2252, i.e. the sensor has a resistance of 2252 Ohms 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.

The MTC-20/2S controller is delivered with a power cord and a user manual. Sensors must be purchased separately.

Options

MTC-20/2S, one channel temperature controller, for heating.

TS-100, sensor, temperature sensor for TC/PTC/MTC systems.

TS-200, sensor, miniature temperature sensor for TC/PTC/MTC systems.
