FIELD: measurement equipment.
SUBSTANCE: measuring vessel with a capacitance sensor installed in the form of a multi-electrode flat-parallel air capacitor, to which a measurement capacitor of available capacity is connected, filled with the investigated gas, and the value of temperature and pressure are recorded. High DC voltage is supplied to the capacitance sensor installed in the measurement vessel and to the measurement capacitor of available capacity. The outlet voltage is measured on the measurement capacitor, and moisture content of the investigated gas is determined according to the temperature moisture characteristic of the sensor.
EFFECT: increased sensitivity.
