DSF - 300 SF6 purity tester
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. 

Two main characteristics, instrument

HDWG-503 SF6 gas Multi-function analyzer(with touch screen , but no printer )

HDSF-503 the multi-function analyzer is the second generation of SF6 gas analyzer of HDGC (Wuhan HengDian GaoCe Electric Co., Ltd) own research and development instruments. This analyzing meter can finish three measurements one time so saving gas used and reducing air pollution. This will save much human energy and the cost. And that’s more, providing a very convenient way to determine the reusability of SF6 gas and on-site validation of recycling efforts.

This meter adopts world famous sensors from overseas. Sensor for moisture is from Finland;

Sensor for purity is from Germany; Sensor for decomposition products is from UK special for

SF6 gas. So HDSF-503 will let our customers enjoy the best price performance ratio.
