If its for a piece of equipment that won't mind it going the wrong way for a short time then I would just do the 50/50 test. If you find it going the wrong direction just change it. No meters required just eyes.
there are two types of phase rotation meters one requires line voltage to operate and the other is self-powered to check motors that are unwired...or going back into service
you use the powered type by connecting the three meter leads to your source voltage usually at the equipments last termination such as a starter or disconnect to verify your incoming voltage...and if you have an arrow on the motor..you then connect the motor leads 1,2,3, for the correct rotation..which as I recall is CCW opposite the shaft end
if you want to check a dead motor and can turn the shaft, use the self-powered type ...again connecting the meter leads to the motor leads and turn the shaft
several are available from Fluke, AEMC, Knopp,.... and Ideal makes a multimeter that you can use
