The field of electrical measurement and electronics continues to grow, with novel techniques and components developed each year. Hence, the Electronics and Measurement Laboratory of the Department of Electrical and Information Engineering has been designed to give hands on experience for the undergraduates in order to reinforce the concepts they learn in various modules such as Introduction to Electrical Engineering, Introduction to Electronic Engineering, Analog Electronics, Digital Electronics, Electrical and Electronic Measurements etc.

The Laboratory enables the undergraduates to be familiarize with various electronic components such as Op amps, BJTs, Diodes etc. And also, it enables the students be acquainted with the state-of-the-art measuring instruments and taking measurements accurately. The Electronic and Measurement Laboratory is equipped with the modern sophisticated laboratory equipment including analog and digital oscilloscopes, logic analysers, power analysers, programmable function generators, dual DC power supplies, FPGA development kits, various electronic components trainer kits etc. Carefully devised laboratory experiments will lead the students through progressively more sophisticated concepts and techniques. They get a chance to analyse and design integrated analog and digital electronic circuits, build them and test them for their intended operation. It will enable the students to build a solid foundation and necessary background concepts and skills needed to develop and use modern electrical and electronic instruments.

The Computer Resource Center and the Information Engineering Laboratory consists of separate space with a capacity of 80 students to work on computer-related activities and an Information laboratory. The main objective of the Computing resource center is to provide students with an interactive space to work on their own computers while the department provides them with a working desk, power outlets, and wired/wireless internet connectivity. This facility is mainly used to conduct activity-based teaching and learning related to course modules that require interactive sessions with the support of computers. For example, Embedded systems design, Digital signal processing, Machine learning, Software projects, Electronics Design, and Computer vision modules make use of this space extensively. Further, as the same space consists of a multimedia projector and a sliding whiteboard, it is used for regular lectures, workshops, and seminars as well. 

The Information laboratory is established in collaboration with the Cisco Networking Academy, Sri Lanka. It comprises several high-end Cisco networking devices and is mainly used for the practical components of networking and digital communication-based modules and to facilitate final year projects. Further, this networking facility can be used in future postgraduate research activities as well.
