Dr.Friedrich Rain Gauge [Posted on 2001-03-22]
I used the Friedrich rain gauge for 9 months. That is until it broke. That was by thermal expansion of the condensate (i.e. the water). The collected rain had frozen. In short, the material of the gauge should have a thermal expansion coefficient greater than that of ice, and not smaller (as it is). The gauge's diameters (collection area versus collecting cylinder cross-section) are chosen so as to provide useful magnification for reading. That is approximately 2-to-1. The calibration is in l/m² (i.e. litre per metre squared, which equals mm [millimetre] of water depth, as if one were to measure it), and also in inches (as if one were to measure water depth). In summary good instrument, also suitable for precision measurement, however unsuitable for use at temperatures much below freezing. I wish this problem will soon be corrected as indicated.
Plastic [Posted on 2001-07-17]
The plastic rain container is good in a warm climate but feels rather delicate. The support rod is somewhat flimsy and doesn't appear to be durable. It is attractive but appears low quality for the $$.
Shoddy rain gauge [Posted on 2001-08-27]
This rain gauge was a disappointment all the way around. First, it arrived broken. Second, it was made of plastic when I had thought (judging by the photo) that it was wought iron. And third, it was marked in meters instead of inches. It was made in Germany and should have stayed there.
REPLACEMENT [Posted on 2001-09-13]
I like the rain gauge. My only disappointment is that I cannot find a replacement gauge. It has broken, but I would like to continue using it. I have tried stores around where I live, but no such luck. Does anyone now how to find them?

This is a real pretty little gauge. It's all plastic and breaks really easily. It would be better if the stand were metal.
