This is a must have tool, very useful in checking phase sequence. These type items make it clear that the rotation is correct. Used often after storm restoration to check the service has been connected correctly for the air conditioners. The easy to use hook up of the leads makes for a sure and true connection and that phase or rotation is running in the correct direction.

first time's a charm
Great rotation meter.No more 50/50 chance of proper phase rotaion. Get it right the first time, every time!A must have for motor loads in which wrong rotation will cause equipment damage.Simple, precise, and long test leads are a plus.
