The capacity of the reservoir of the gage is up to 200 mm and filled with DI water. I've been collecting data to evaluate the performance of the gage, and the results look pretty good so far. It measures grass reference ET (ETo) and can also be adjusted to measure alfalfa reference ET (ETr) by changing the canvas cover on top of the gage. The info of the manufacturer is as follow: C & M Meteorological Supply 8150 Poco Road Colorado Springs, CO 80908 Voice: (719) 495-8878 Fax: (719) 495-8960 Suat [Bruce comments Thanks Suat, we look forward to including a link to your results on the et page.
