Recent interest in a simple low cost temperature controller to maintain small and medium sized objects at physiological temperatures was there a reasoning behind the development of the Physitemp MTC-1 microtemperature controller.  Utilizing a precision highly stable platinum RTD as the feedback sensor, this inexpensive controller will display and maintain a set temperature within + or - 0.1 °C.  The controller is designed to operate from a 12 V DC supply and can control an output current up to 4 A (50 W).  It can also be used with an input voltage between 6 V and 24 V DC for both lower and higher power applications (up to 90 W).  A 1/2 inch backlit LCD readout provides continuous display of temperature with 0.1 °C resolution.  The set point is easily adjusted from just above room temperature up to 99.9 °C via a 20 turn potentiometer.  A momentary switch allows the user to toggle the display between the set and run temperatures. The controller is ideal for maintaining the temperature of 60 cc perfusion syringes and small heated surfaces. Its compact size (5 1/2" long × 2" wide × 1" deep) makes it ideal where space is at a premium.
