If you boiling water tested your wireless thermometer probes for accurracy and you are getting a 320F temp then I congratulate you! lol
yeah I think but could be wrong that they have a automatic shutoff if they reach a certain high temp so they don't get damaged. again i could be wrong about this.Watch that high temperature, I have read on this forum that MES ‘s aren’t built to handle temperatures over 300F for any length of time.
The highest temp my MES has achieved was 311.
