You can buy these with a calibration certificate for like $70, but I skipped the cert. Should be the same quality, cost me $16. I chose the version with the superior units of measurement.

They could measure themselves and just send the ones that meet the criteria for certification by someone else. Anyway it’s a funny tinfoil theory and they are probably all good quality.
Yeah good point. I’ve been growing my collection of tinfoil hats lately.
