The EC-400 electrochemical oxygen analyzer is an online analyzer that
uses a new type of |
|
intelligent detection
instrument combined with imported sensors and a single chip computer,
with |
|
a% display. It 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 a KOH solution. Using this method for |
|
oxygen measurement, the
electrochemical oxygen analyzer can be unaffected by the reducing gas
|
|
in the measured gas,
eliminating many sample gas processing systems. |
|
◆
The instrument adopts a new imported fuel cell oxygen sensor |
|
◆
The instrument adopts a large screen LCD display screen with full Chinese
operation menu |
|
◆
Real time clock display, with 64 paperless data records and storage in
the background |
|
◆
Fast measurement speed, simple user calibration and debugging，Available
standard gas for online calibration |
|
◆ The sensor is not
interfered by impurities such as H2, CO, CO2, H2S, NOx, etc |
|
◆
The output current is 4-20mA, which can be connected to a PLC |
|
◆
Upper and lower limit alarm points can be set, with alarm contact
output |
