Hand-crafted, glass rainfall measure calibrated in millimetres. For use with any 5" copper rain gauge: simply pour the contents of your rain gauge’s internal measuring tube into the CM1013.

Hold the CM1013 funnel vertically at eye level and read off the measurements. Depending on how much rain has been collected you may need to do this more than once.

After taking your daily rainfall readings, replace the internal catchment funnel into your rain gauge and store away your 1013.

Did you know that we offer three different Glass Rainfall Measures? The measures in inches whilst the measures in mm, both with a flat base. The measures in mm with a tapered base, ideal for accurately measuring small amounts of precipitation.
