Also, this device can be called: Barguzin1, Barguzin 1.
Hygrometer coulometric Barguzin-1 - portable instrument for measuring the volume fraction of moisture in the air, nitrogen, oxygen, hydrogen, helium, and neon.
Hygrometer has ranges measurements of the volume fraction moisture (EFA) in gases - 0-2 m -1, 0-10 m -1, -1 million 0-100, 0-1000 ppm -1.
Portable hygrometer made constructively in two separate blocks: the transmitter and power supply. In converter integrated independent power source that allows for measurements without connecting it to the network.
For recording hygrometer used motorized potentiometer KSP2-005I.
