An atmospheric electric field meter

The Ryabina atmospheric electric-field meter is described. Results of its comparative tests are presented, which demonstrate that it is superior to its foreign analog, that is, the EFM550 electric-field meter (from Vaisala, Finland), in a number of parameters. The dynamic range of the meter is ±30 000 V/m, the discreteness of measurable values is 1 V/m, and the measurement rate is 10 s–1.
