is this chromatic? Can I set the tuner to other than 440?

Yes, chromatic. Calibration range from 410-480 Hz.

Is it auto calibration for each string?

I take it you're asking whether it auto-detects the pitch for each string, rather than the user having manually to select it for each string. Yes! It's really simple to use.

Is it safe to leave in a guitar with nitrocellulose finish?

I have had it in my Taylor for 10 months and just removed it to move it to another guitar. No issues with it affecting the finish. As with most anything that can attach to your guitar. Know what finish was used on it, guitars with nitro-cellulose finishes may show damage from the rubber pad on this tuner. I don't leave anything physically attached to my Martin.

what are the dimensions of this tuner? I need to check if it can fit with the sound board bracing of my Aoud before buying it. Thanks

This hits the bracing in one of my guitars. But this tuner is so tiny, just move it along the sound hole until you find a better fit. On a flat top guitar, this'll work wherever you place it around the rim of the sound hole. Your sound hole is 360 degrees. Just find a spot where it doesn't hit any bracing and you have a good line-of-sight to the display.
