Measurement Techniques Aims and scope

We describe the method of aspiration capacitor intended for the complex verification and calibration of highly sensitive equipment aimed at the measuring the specific electric conductivity of air (up to several fS/m) and used in the course of sounding of the bottom layer of the atmosphere and air in sealed compartments and clean rooms. We present a description of the engineering tools used for testing, verification, and calibration of these measuring instruments. We also present a structural scheme and describe the principle of operation of a high-stable generator of specific electric conductivity of air developed at VNIIFTRI. Finally, we give the results of measurements of the specific electric conductivity of air performed with the help of the described measuring instruments and show that the relative error of measurements does not exceed 2.5% for a normalizing value of 40 fS/m. This enables one to perform the verification and calibration of the existing types of measuring instruments.
