Hi - where can I get a good-quality air thermometer, i.e. that is
accurate, robust, and has a big range (ideally -50 to +50 but -40 to +40
would do [°C]).

I don't trust those cheapo ones with a bimetal coil and attached needle.
I'm not too sure of the cheapo LCD-display ones either.

Hi Hatch.

Theres no such thing unless youre willing to pay real money. The usual
household glass tube ones are always fragile, the metal spring ones
can be very inaccurate. The digitals are much better, but again arent
exactly built to last.

If youre serious you need a comercial electronic thermometer, but
expect to pay 3 figures. It will however give you everything youre
asking for, plus at least 0.1C accuracy.

There were secondhand portable units - about the size of a DVM - being
offered on eBay by the makers complete with new calibration certificate.
Think they went for about 20 quid.
