Single crystal is a very essential for researchers and laboratories; we grow a large single crystal of TGS ferroelectric material, by using a low-cost automatic crystallizer unit controlled by a computer. The program used enables user to modify growth conditions such as decrement rate of temperature and motor speed. The study of the produced sample is important to judge the performance of the constructed unit. A well-known TGS sample was grown. Some physical properties were measured and they are all in a fair agreement with published data.

Instrumentation Physics today holds high position in technology, improve the measurements to get more focus on areas which is out of reach ago, low-cost and computerized systems are more required than ever due to current expensive technology. Computer saves time and reduces errors, suitable for long-time experiments, the track of computerization systems beside keeps it low-cost with good quality grows up everyday. This work aims to present low-cost computerized measurement system for two of famous physical properties in Condensed Matter.
