The EC-400
Electrochemical Micro Oxygen Analyzer is an online analyzer that uses a
new type |
|
of intelligent detection
instrument that combines imported sensors with a single chip computer,
|
|
with ppm display, and is widely
used for the detection of oxygen content in industrial production |
|
processes such as air
separation and nitrogen production, fertilizer, petrochemical industry,
and |
|
biological fermentation. The
fuel pool oxygen sensor is composed of highly active oxygen |
|
electrodes and lead electrodes,
which are immersed in an electrolyte solution. Using this method |
|
to measure oxygen can be
unaffected by the reducing gases in the measured gas. The EC-400 |
|
electrochemical micro oxygen
analyzer eliminates many sample gas processing systems. |
|
◆
The instrument adopts a new imported fuel cell oxygen sensor，Fast
measurement speed, simple user calibration and debugging |
|
◆
The instrument adopts a large screen LCD display screen with full Chinese
operation menu |
|
◆ The sensor is not
interfered by impurities such as H2, CO, H2S, NOX, etc |
|
◆
Real time clock display, with 64 paperless data records and storage in
the background |
|
◆
The output current is 4-20mA, which can be connected to a PLC，
Available standard gas for online calibration |
|
◆
Upper and lower limit alarm points can be set, with alarm contact
output |
|

The following
gases have no effect on the measurement results |
|
HCCH |
Air |
NH3 |
Ar |
C2H8 |
CO |
H2 |
He |
|
N2 |
C3H6 |
C2H4 |
SF6 |
ASH3 |
PH3 |
SIH4 |
HC |
|
CH2O |
|
|
|
|
|
|
|
|
The following gases have no interference with the sensor signal
output, but exposure to the above recommended values (regardless
of time and concentration) can reduce the sensor life by 3-4
months or even fail |
|
C4H6 |
CO2 ＞1000ppm |
HCL＞1000ppm |
HCN＞1000ppm |
HF＞1000ppm |
H2S＞10ppm |
SO2＞10ppm |
|
|
The
following gases have a small impact on the sensor life, but
cross interference with the oxygen sensor results in a reading
deviation (1 ppm causing 2 ppm error) |
|
CL2 |
NO2 |
