Aliexpress Fluid Bed roaster 300g


...this picture...
? forgot to attach ?

Looking again at OP pictures, I don't see any voltage engraving near the knobs, but FAN and TC.
Are you sure that what you believe to be voltage aren't degrees ?!!! 220V ... 220 C degrees, they match a lot the range and could fool you thinking you are varying volts, while you could have inside a PID and what are you changing is the setpoint !!!
It make a lot sense to me such design, instead letting you change a "voltage", that actually tell nothing to most roasters...

Here is the picture, sorry. No I'm not sure at all, but the voltage kinda fits my experience how the heater reacts when i turn the know.

The seller also told it it shows voltage when i asked. I think mine is the 3 version of this roaster, the older one looks like this and there it says voltage.

Also i have a hatch on the backside i open and i think tracked the thermocouples over the heater, one goes out to my usb dongle and the other one goes to the left display. For a pid it must have a thermocouple right?

Edit: I really cant upload the pictures correctly, sorry

Yes, sadly is voltage...

It is too cheap to be a true RMS meter, so is highly questionable what are you really measuring there.

You can read here what are the quirks with AC voltage measurement:

Your links to the images in this post seem to be bad. The first does not have a supported file extension (8885194891294531103.webp).

Your earlier post with many images is OK. All used .jpg files.
