Portable oxygen analyzer for monitoring of environmental oxygen content in laboratories
Portable oxygen monitor for monitoring of environmental oxygen content in laboratories
Applications
It is widely used in the monitoring of environmental oxygen content in hospitals, factories, hotels, schools, laboratories, cold storage and other environments.
Instrument features
a) Friendly man-machine dialogue menu, intuitive and convenient operation;
b) Modular design, the user can choose the altitude measurement module;
c) Compared with electrochemical and ultrasonic, it has a long service life and fast response;
d) The sensor is not powered, does not consume, has a long service life and is easy to maintain;
e) no reference gas is required, independent of the operating environment oxygen concentration;
f) The calibration interval is long, high precision, stable and reliable;
g) High-precision temperature automatic compensation system to eliminate the influence of ambient temperature;
h) The measurement range is 0 ~ 40.0% O2 wide.
Oxygen concentration monitor workflow:
The user only needs to install the oxygen concentration monitor on the wall of the room by screws. The monitor contains an oxygen sensor, an altitude sensor (optional), an atmospheric pressure sensor (optional), a temperature sensor (optional), and humidity sensor (optional), The monitor can read the required parameters on the LCD screen after it is energized and preheated.
Automatic control of oxygen concentration:
The user can freely set the upper and lower limits of the oxygen concentration control range on the oxygen monitor, then the monitor automatically outputs the passive switch signal according to the set value. According to the passive signal, t the user can realize the automatic control of oxygen concentration in the room.
