Trouble free performance

Our instruments are highly efficient when it comes to performing experiments. We have designed our instruments in such a way that the students feel comfortable and highly motivated while working on our instruments.

Robust and Strongly built

The material used for making our instruments is best in class. We employ high quality optics and superior machining for better accuracy and stability throughout the lifetime of our instruments.

Thorough Testing

Testing and checking at every phase of the development process makes our instruments highly precision and accurate. Each and every instrument has to pass through various tests during and after development hence making it perfect and accurate.

About Us

We have been making scientific instruments for physics labs since 1962. Manufacturing was started by Late Sh.Mohinder Singh. The instruments made by him were Sextants, Barometers, Earth Inductors, Dip Circles etc. Now Sigma Instruments Co. is being run by Mr. Harbhajan Singh(MSc Physics). His endeavor has always been to design and improve the instruments, so that their operation becomes easy, give accurate results and are students friendly. We use right material and components for all our instruments. Our instruments are quality checked and tested thoroughly to ensure their accuracy and proper functionality. Our instruments are being used in almost all physics labs throughout India marketed by different dealers. Our instruments carry special features which make them different from the routine type of instruments and are always the first choice of quality seekers!!
