What specific tool or gauge can I use to measure rpm. I want to check the rpm of my generator.
I know some of the Flukes can with an inductive pickup, but I did not want to go that route since I have a Fluke though it doesn't offer that option.
A tachometer, and then you have to figure the ratio of the pully...Never tried tried that...Sounds interesting though...

I should have been more specific about the generator. It's a Mutliquip GA-3.6RZ which is a small emergency generator used to produce electricity when power is out due to storm damage.
The motor is a Wisconsin Robin W1-280, has 273cc and makes I think 7 hp.
Well, if it was a larger generator you would install a dedicated frequency meter - many larger units include one.
Nothing wrong with a good old vibrating reed frequency meter. Been pretty much the same insided since the 1920's....
The downside is cost. Stichco still makes a good unit, but it is about 125 bucks. Nice units, OEM in large Multiquip gensets.
Of course you could put the 125 toward a new Fluke, but you won't leave the fluke connected to the genset all the time either.....
Your call. If the genset is connected with a transfer switch (permanent installation) I would recomend a dedicated frequency meter as well. Makes a good 'quick check' along side a voltage meter. Kind of like having a manifold set.

Thanks to all who responded.
Looks like I have lots of options. I like that idea of the Hertz meter since circuit breaker box is set up to have generator connected to it so generator will power anything I want except 220. No A/C Of course with the full power 120 volt output of 27 amps and 3400 watts I have to select what I want to use and can not use that much at the same time. But when you don't have power for a couple of weeks or more you're are more than happy having light switches that actually will make the light bulbs go on and a refrigerator and freezer that function.
I bought this generator in September of 1989 two days after Hurricane Hugo. Below is a photo I just took, with the new wheel kit I installed after making sure it's in perfect running condition and ready should the need arise.
My whole neighborhood has underground cable but, but after Hugo we still didn't have power for 2 1/2 weeks. I guess all the big high tension stuff is all above ground. I remember the towers that brought power from the other side of the river where gone and had to be replaced.
I remember it was real wierd to go over one of the bridges by my house 2 nights after the storm and look towards downtown Charleston and it was completely dark, you turn 360 degrees and wherever you looked it was dark, that's the way it looked in 1670 when the first settlers came here.
You guys know I'm joking with the GPS. Actually, I like the inductive pickup idea. They sell these really cheap for use on bicycles. They are supposed to connect to a spoke of the wheel. I suppose that you could tape it to the shaft somewhere on the generator. The ones that I have for my bikes are adjustable for distance. If you know the distance of 1 rev, then its easy to get accurate rpm from that.
