My Max/min thermometer does not give equal readings onthe two
scales.Any
ideahow I can equalise them please? It is a mercury
thermometer
with
markers
in eachsection of a U-shaped tube.
These can be reset by an inbuilt magnet at the back.

That usually means that the glassware is not mounted correctly i
the
frame. Try moving it slightly up and down till the readings are
the
same.

It's quicker to buy a new one, they cost almost nothing nowadays.

Unfortunately they almost all suffer from the same problem,
{:-((

Not all in Dutch DIY places.

You're lucky there.
