Important points to consideration when selecting a temperature calibration metal block bath for calibration by comparison:

A temperature probe is calibrated in a block by comparison with a known reference thermometer. For accurate calibration, the two thermometers must be in thermal equilibrium which requires that they are as close as possible over their full length and ideally of similar thermal mass, and response time.

Having both thermometers close together in the same insert is generally accepted as far more accurate than relying on a  block's control probe, which may be located away from the thermo well.

Some block designs rely on a built-in probe as the reference and although a display offset is used, it can only be correct for one temperature.

The separate reference thermometer, with no limitations of being built-in, is a much better option as it is placed close to the thermometer under calibration and can be easily calibrated and re-calibrated over a wide temperature range to traceable national standards.

So, instead of having to send the calibration bath away for annual re-calibration, you need only to send your external reference thermometer away for re-calibration.
