Ventilation is key. If you can exhaust the fumes to a window with a fan that would be ideal, and a respirator should be a secondary option. Though if you must, you need something with OV on it for organic vapours.
That’s not full auto! This is full auto!
Keep in mind IR thermometers are sensitive to the reflectivity/emissivity of the materials they are used on, and the shiny PEI surface can be a bit tricky. Try measuring the temperature of a mirror that your warmed up with your hand and you’ll see a similar problem.
If you want to test more accurately, put some matte tape on the bed and then measure the temperature then.
That said there is also a chance for the heat bed to be a bit lower than target temperature, since the temperature control and feedback occurs at the bottom of the bed where the thermistor is, not at the top, and is separated by a layer of magnetic adhesive and coated metal.
