1, functional overview
The purity of quantitative instrument for Germany SAMRTGAS infrared sensor as the core,
the high precision AD sampling, high-speed ARMCPU,
makes the sampling data more real and reliable.Instrument USES the color LCD touch screen shows, friendly interface beautiful, easy to operate.
German smartGAS company SF6 sensor principle is a principle of infrared spectrum, also is the principle of laser!
Compared with the principle of electrochemical, SF6 infrared sensor (sulfur hexafluoride) sensor with high reliability, long life,
high cost performance.Alcohol, H2O and CO2 gas interference.
It is widely used in electric power equipment of SF6 gas leakage monitoring alarm system (0-1000 parts per million (PPM),
SF6 leak detector (0 to 50 parts per million (PPM), SF6 leak detector purity analyzer (0-100%).
Compared with single wavelength single beam, double wavelength double-beam technique can be avoided because the light aging,
sampling pool and pollution caused by the surface of the detector drift.
Reference channel by modulation of a specific wavelength of monochromatic light not absorbed by measuring gas produced.
It produces a stable signal, this signal is only affected by external changes, not affected by the measured gas.
1, the principle of infrared absorption spectrum (NDIR)
2, dual wavelength with temperature compensation
3, high reliability, no cross reaction with other gas.
4, compared with the electrochemical sensor, sulfur hexafluoride sensors, infrared sensor a decade of life
5, high cost performance, affordable preferential price.
6, compared with the electrochemical sensor, sulfur hexafluoride sensor save after-sales maintenance
7, no radiation source, no harm
8, micro structure, low power consumption
9, digital and analog output.
