Prospects for the development of hygrometry in the East-Siberian branch
- Improvement of the National primary standard of gas humidity GET 151:
- reproduction of three highly sought units of gas humidity: relative humidity, molar (volume) part of moisture, dew/frost-point temperature;
- broadening of measurement range of GET 151;
- broadening of operating ranges of temperature up to+ 90 0С;
- control automation of operating process, information collection and processing of GET 151;
- development of standard generator of low dew/frost-point temperatures;
- broadening of operating ranges of temperature up to -70 0С (- 90 0С);
- mutual comparison of standard generators of GET 151;
- productivity boosting of calibration works by three times.
