Phase sequence testing is crucial for many three-phase loads. Improperly connected motors can result in reverse rotation, which can damage the equipment powered by the motor. Ensure electrical equipment is correctly and safely connected with Amprobe’s PRM-4 Phase Sequence and Motor Rotation Tester.

This product is user friendly with fast results
In an industrial environment three phase motors are predominant and having this phase sequence tester in my tool bag has made me more efficient at my job
✔ Yes, I recommend this product.

work great
we just got the amprobe phase sequence and motor rotation tester to test pump motors and has work great for us
✔ Yes, I recommend this product.

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.
✔ Yes, I recommend this product.

Must have tool to check phases
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.
✔ Yes, I recommend this product.

Emergency Generator Must Have
This tester will allow you to hook up your 3 phase generator or motor and know the rotation without having to turn the equipment on and guess. In the case of emergency generators matching your utility phasing, you need to know the rotation. Trust me.
✔ Yes, I recommend this product.

Great tool!
I got this used from a friend when I went into the power generation field. on mine the motor rotation tester has never worked, but I give it 4 stars for not failing meand a coworkers fluke did resulting in parallelling 2 generators with opposite rotations… This is a tool I would purchase new for myself if it ever needs to be replaced. I really love the phase sensing lights and the rotation light, lets me see I have power on all 3 phases and the rotation.
✔ Yes, I recommend this product.

Easy to use
When I bought this meter I was looking for a just a rotation meter. After seeing all of the features, I couldn’t pass it up! I’ve used it a few times, was completely user friendly and easy to figure out. Basically a plug n play console. I’d recommend this meter for Sure!
✔ Yes, I recommend this product.
