    hello
    i recently purchased a combi microwave with a ‘convection’ mode. I also have a normal convection (fan assisted) domestic oven. I purchased a K-type thermometer + thermocouples. I found the temperature in convection mode for the combi microwave never reached the preset temp e.g. when set t0 150oC, the temp measured in the middle of the chamber was around 96oC and about 100oC near the bottom over a ‘cooking ‘ period of 5 mins. When I did the same test with my domestic oven when preset to 180, 220 and 250oC, the measured temperatures were approx. 181, 219, 243 on average with +/- 1-3 % error.
    Are there any rules/legislation regarding what should be the difference preset vs actual temperatures and amplitudes around the mean should be for natural and fan assisted convection domestic ovens and convection mode for combi microwave ovens? Many thanks

      It’s a help to have measured these things as that’s what matters. When I used more than one device I was left wondering is there were regulations on calibrating oven thermometers. And I wondered where exactly the probe needs to sit. Do keep investigating and ask if the manufacturer has guidelines as you’ve hit on a ‘consumer issue’.
