Phase Sequence Indicator
No. 500 - Knopp Incorporated (Tesco)
The TESCO Phase Sequence Indicator meets the need for an instrument that makes basic phase sequence indication as easy as 1-2-3 (or 3-2-1). Catalog No. 500 is lighter and more compact than any other indicator available. Phase sequence is simply indicated by two neon lights. One light is for phase sequence 1-2-3 and the other light is for phase sequence 3-2-1.
