Central scientific instruments organisation

Central Scientific Instruments Organization (CSIO), which is basically situated at Chandigarh, is a constituent laboratory of the Council of Scientific and Industrial Research (CSIR), it is a national laboratory dedicated to research, design and development of both scientific and industrial instruments. It is a multi-disciplinary and multi-dimensional crown industrial research & development organisation in the country to maintain the growth of the Instrument Industry all over India which covers a wide range of applications and uses. CSIR CSIO has worked in various areas of instrumentation and skill development programs by awarding diplomas through Indo-Swiss Training Center (ISTC) situated at Chandigarh also established centres at Chennai and Delhi to meet the regional demands.
