MTC-20/2SD – Temperature Controller

Add to Wishlist Remove from Wishlist

Desktop temperature controller

  • Temperature control in sensitive electrophysiological recordings
  • No switching artefacts due to analog control
  • No electrical noise due to linear power supply
  • Easy perfusion heating

About MTC-20/2SD

The MTC-20 temperature control system is designed for heating purposes in electrophysiological experiments with small or medium power requirement. The device has one temperature control channel and one additional thermometer/sensor input. The system guarantees low noise operation and has special protection features to prevent the connected heating elements from damage.

The analog design allows noise-free heating of sensitive preparations for low-noise electrophysiological recordings.

The system incorporates two electronic thermometers for small temperature sensors (standard is R2252, i.e. the sensor has a resistance of 2252 Ω at 25 °C or optional PT100, i.e. the sensor has a resistance of 100 Ω at 0 °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 outputs are short circuit protected, the output power is limited electronically. The maximum output voltage is approximately 12 V, the current is limited to 1 A.

The system can be connected to the thermistors / heating elements in two ways:
– Using separate cables for the sensors and the heating element or
– Using the ALA DIN cable assembly that connects both, sensors and heating elements, e.g. ALA HPC-G

The temperature controller is delivered with a power cord and a user manual. Sensors must be purchased separately.
