This video should help you:
I have one of the cheaper PAR meters. It was like $180 on Amazon. It seems pretty accurate against the light manufacturer's PPD diagram. I get the desire to have a PAR meter, but honestly it's not a necessary expense. Do your best with the PPD charts, it'll be fine. With quality LEDs these days lighting shouldn't be your bottleneck. There's a few apps available to download that will help with Lux and conversions so you can check yourself and get some peace of mind.
