Hygrometer Barguzin-1
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.

Specifications hygrometers Barguzin-1:

Measuring range - from 0.2 million-1 to 1 billion -1.
Voltage - 220 ± 4,4 V.
AC frequency - 50 Hz ± 0,5.
Duration, powered by batteries - 5 hours
Power consumption - 120 watts.

Sample gas flow:
- Through the sensing element - (100 ± 1,6) cm 3 / min;
- As measured through the by pass - 3000 cm 3 / min;
- When the bypass purge air, nitrogen, neon and oxygen - 10000 cm 3 / min;
- Bypass by blowing hydrogen - 5000 cm 3 / min;
- Bypass by blowing helium - 15000 cm 3 / min.

Dimensions converter - 420x270x300 mm.
Overall dimensions of the power supply - 310x200x220 mm.
Weight converter - 18 kg.
Weight PSU - 8 kg.
The principle of operation of the hygrometer based on a continuous film of moisture absorption quantity of sorbent from the continuous flow of a predetermined and accurately analyzed while gas and electrolytic decomposition of water absorbed into hydrogen and oxygen.

Operating conditions hygrometers Barguzin-1:

The sample gas temperature - from -50 ° C to +60 ° C.
The ambient air temperature - from -50 ° C to +50 ° C.
Relative humidity    Ambient air - up to 98% at temperatures above +35 ° C.
Atmospheric pressure - from 90.0 kPa to 104.5 kPa.
Sample gas pressure - 0.03 MPa to 40 MPa.
Optional user of the hygrometer may include automatic potentiometer stimulus gas flow with a mounting kit.
