Buying Guide: What the Ratings Mean

Keep these points in mind before you buy.

NSF, NIST and IP ratings

NSF listings relate to food-service sanitation, NIST-traceable certificates document factory accuracy, and IP ratings describe water resistance.

Calibration certificates

Some brands include a NIST-traceable certificate, such as ThermoMaven and ThermoWorks Sizzle; you can still check any model in ice water.

Speed and accuracy

Fast readings mean less heat lost from the grill or oven. Most good models list accuracy within about 1°F.

Rating Check Tips

Verify before you buy:

• Look for the certificate.
• Check NSF on the listing.
