Hi Tapio,
Re: Thickness gauge - is there enough weight in the plunger to eliminate the spring? On my dial gauge, I just took the spring out and gravity drops the plunger.
On that site were a couple other tools of interest. Wind speed indicator and IR thermometer. Both at bargain prices.

Found a new neat toy from HobbyKing, a digital thickness gauge. Darn
cheap, so I bought one just to test it out. Seems to work pretty good.
The zero setting is typically about 0.01mm on negative, but as this is
regular, it is easy to take into account. Besides, even though the
resolution of the gauge is 0.01mm, the accuracy is (according to the
sticker glued on top of older text in the package) 0.1mm. Seems to be
better, but anyway which meter would be accurate to the resolution anyway?
There is one shortcoming, that needs modification: the standard spring
closing the claws is way too strong, it squeezes rubber and crashes thin
balsa strips. Luckily, the gauge can be quite easily taken apart (the
back keeps in place with thin plastic pins), and then the spring can be
replaced. The original spring is 0.25mm wire, for the start I replaced
it with a rubber loop, but maybe a 0.15mm spring might be better.
I recall reading in the comments of the unit that some were not as good
as others, but the unit I got is quite ok.
Ah yes, a link:
