Where to buy thermogravimeters
 

Does anyone here know where I can buy thermogravimeters?
They are used to monitor samples against different time or temperature and different atmospheric settings.

Our old one broke down on us, thus we need a new one for our lab because we test samples under different conditions, to see how much they can endure.
I found some here at linseis but I can't find any reviews online. I suppose it's too specific. by any chance, is anyone here an expert on thermogravimeters?
