China Jfa307 Industry Liquid Pipe Dissolved Oxygen Meter Analyzer

JFA307 industry liquid pipe dissolved oxygen meter analyzer
Description:
Dissolved Oxygen analyzer adopts fluorescence method to measure dissolved oxygen.
The cap of the sensor is covered by a luminescent material. Blue light from an LED illuminates the
luminescent chemical.
The luminescent chemical instantly becomes excited and releases red light. The time and intensity
of red light are inversely proportional to the concentration of oxygen molecules, so the
concentration of oxygen molecules is calculated. With this method, oxygen consumption won't be
produced in measuring, and the data is stable, performance is reliable, no interference, simple to
install and calibration.
Features:

The sensor adopted new type oxygen-sensitive membrane, equipped with NTC temperature
compensation function,
the result is with good repeatability and stability.
oxygen consumption won't be produced in measuring, have no require of flow velocity and stirring.
Breakthrough fluorescent technology, no membrane and electrolyte, maintenance free basically.
Internal function of self-diagnosis to ensure the accuracy of data.
Factory calibration, adjusting free in a year, support calibration at the site.
Digital sensor with strong anti-interference capability and far transmit distance.
Standard digital signal output can make integration and networking with other equipment without
sensor.Convenient to install sensor at the site, plug and play.
