A simple technique for the automatic opening of a wet deposition collector

The description of a simple device designed for the automatic opening of a lid of a collector at the beginning of a precipitation event and the results of its testing are presented. This device can be produced from minimal improvised means, is inexpensive and simple in operation in comparison with known analogues. Effective protection of the collector from penetration by dry deposits such as dust, insects and plant detritus prior to the precipitation event along with minimal sample losses during 20 precipitation events was confirmed.
