How read the frequency of crystal

Possibly not all of them, I only have that Hantek.

This surely applies :-+
As for the Hantek, its "measurements" panel also only shows frequency to 2-3 decimal digits, but there is an additional trigger event counter which is always visible and provides several digits of resolution at high frequencies. IIRC its gating interval is 1s and it doesn't do reciprocal counting, but that's good enough for MHz crystals.
