Tek   Know TC150 
Temperature Calibrator
TC150 is a portable dry block calibrator with temperature range from -40°C below ambient 
to + 150°C. The special designed controller and the aluminum low mass well gives the unit   
quick responds when the set temperature is changed. Peltier elements are used to generate 
heat or cold in the well. The internal microprocessor change the controller parameters 
depending of the set point and temperature of the internal  sensor are shown at the internal 
LCD display. Resolution is 0.1°C. Accuracy is ±   0.3°C and stability is ± 0.03°C. The unit is 
equipped with an RS-232 serial   interface and can easily be connected to a PC and the SC200 
software. TC150 is   supplied with a rugged case, traceable certificate and necessary   
equipment.
