It measures in hundredths of an inch, or millimeters, and has an eleven inch capacity (27.94 centimeters). It's also useful for measuring frozen precip. FYI this thing is much larger than it appears in the picture. Under $40 US.
Many of you already have a backup gauge in place, I'm sure, but for those of you who are still looking for one, this is one to add to your short list.
When a Great Blue Heron left its calling card in my VP2 last week, at the start of a rain storm, the above gauge saved the day.
A good manual gauge is also great for calibrating your tipping bucket weather station. Tipping buckets can be overwhelmed during heavy rainfall. Having a this manual gauge nearby will give you the actual rainfall amount. And if your tipping bucket freezes during precip, just bring the manual gauge indoors after the event and melt down the contents for an accurate rain equivalent. This gauge disconnects (and reconnects) easily from its base.
