The chemical property of hydrogen peroxide is unstable, and
it is generally stored in the form of aqueous solution, and its aqueous
solution is commonly known as "hydrogen peroxide". Hydrogen peroxide
gas molecules for the chair structure, not pure gas stability is poor,
spontaneous disproportionation decomposition into water and oxygen, can not use
the preparation of bottled gas standard material method to produce and store
hydrogen peroxide standard gas.
For a long time, there is no method to prepare H2O2 standard
gas, so the calibration laboratory uses SO2 gas standard material to calibrate
the H2O2 detector. However, the concentration correlation coefficients of SO2
and H2O2 are not the same for different instruments under test. The correlation
coefficient of the same instrument is not constant as time increases; For
spectral H2O2 analyzer, the calibration results with SO2 standard gas show
greater deviation.
Under such circumstances, EUCA Technology Co., Ltd.
cooperated with experts and scholars from the Chinese Academy of Metrology and
other units for four years, and finally developed the SSG H2O2 Gas Detector Measurement Standard. The device has been calibrated by the Chinese Academy of
Metrology, and its uncertainty is better than 5% (k=2).
This is China's new contribution to the
international metrology community.
Product advantage
- The SSG-H2O2 gas detector standard device uses intelligent
automation technology and has the function of remote operation. Whether the
operator is on a business trip or in a different laboratory, the device can be
operated as long as the operator has Internet access. This feature also
facilitates remote training and inspection.
- The SSG-H2O2 also has a simple operating interface. Users
only need to enter the set H2O2 gas concentration value and click the
"Start" button to work.
Product value
- Accurate quantity value: dynamic and stable occurrence, easy
to trace
- Wide concentration: up to 2000 ppm gas is produced
- High efficiency: Can be operated remotely - travel? Does not
interfere with instrument use
- Corrosion resistance: Corrosion-resistant elements in contact
with corrosive gases
- Low cost of use: H2O2 solution can be added repeatedly
- Gas temperature control: the outlet temperature can be
controlled to ensure that the high concentration does not liquefy
In view of the advantages and value of SSG-H2O2 hydrogen
peroxide gas detector calibration device, it is widely used to carry out
hydrogen peroxide gas tests, or hydrogen peroxide gas sensors, alarms,
analyzers for verification, calibration or other performance tests.
With
its unique advantages and excellent performance, the product has attracted the
attention of the metrology class, and won the recognition and high evaluation
of users!
