FIELD: measurement technology, hygrometry. SUBSTANCE: invention refers to sensors of gas humidity operating in main gas pipe-lines of natural gas under pressure. Device has thermostated saturator which input is connected to gas source and which output - to capacitor via spray scooper. Unit for anchoring of calibrated (graduated) sensors and temperature meter which electric output is coupled to cooler of capacitor via thermal regulator are mounted at output of capacitor. EFFECT: enhanced functional reliability and accuracy of device. 2 cl, 1 dwg
