RA-912F based on advanced laser measuring SF6 purity of principle, only SF6 has spectral band absorption characteristics, interference from other components, to fully meet all kinds of electrical equipment using sulfur hexafluoride filled with gases such as N2 or CF4;
Unique advanced cross-sensitivity to measure decomposition algorithm, a large number of laboratory data foundation, integration of linear algebra algorithms to calculate the results more accurate;
Classic polymer film humidity measurement SF6, when ambient humidity changes, the moisture sensitive components of the dielectric constant is changed, a corresponding change in the output electrical signal.
- Using the principle of SF6 gas spectral absorption measurements, rapid, without the interference of other gas components to better meet the needs of the site.
- SF6 purity mass ratio (g / g), volume ratio (mol / mol) switch at any time to display, can be directly controlled national standard, eliminating the volume and mass ratio conversion link.
- Large range forecast, protect the sensor.
- Massive experimental data, based on real-time traffic temperature compensation.
- Sensor cross-sensitivity matrix removal.
- Unique patented drying protection device.
- Boot zero, the slope of the self-calibration.
- Micro water under standard conditions automatically converted.
- Internal configuration filter.
- Each measuring gas path individually designed to ensure accuracy, independent regulation is more suitable for field use.
