Kyoritsu phase rotation testers — also known as phase sequence testers or phase indicators — are used during commissioning and maintenance of three-phase motors, generators, and electrical panels to verify correct phase sequence and prevent reverse rotation damage. The KEW 8031 and KEW 8031F are contact-type models for standard 3-phase systems, while the KEW 8035 is a non-contact safety phase indicator for use on high-voltage systems where direct contact is not permitted. All are compact, robust, and suitable for industrial and utility environments across India. Backed by a 3-year warranty and available from KEW India — the authorised Kyoritsu Japan products in India.
