Scientific equipment and services and techno instruments are both iso 9001: 2000 certified company engaged in manufacturing of complete laboratory experiments measuring instruments for bs and ms laboratories of physics, electronics and electrical engineering.
The company manufactures laboratory control instruments. Proportional-integral-derivative [pid] control is used in industrial processes like chemical, petroleum, power, food and manufacturing industries. These systems are usually slow, complex and are characterized by relatively incomplete or uncertain mathematical description. The pid controller, parameters of which may be adjusted experimentally, is therefore particularly attractive in such situations. The features of the pid controller are,
