Product Details

Online trace oxygen analyzer can work in the air for a long period without damaging the serving life. Built-in function of temperature compensation could reduce the influence from the changes of environment temperature on the measured accuracy. The new-type longevous zirconia detector is with no power on no consumption, high accuracy, a rapid response speed and high sensitivity for features, etc.
Online trace oxygen analyzer main features:
1. The response speed is rapid and the lowest measurable unit is 0.1ppm;
2. The function of storing data automatically allows the users to look through the historic data freely;
3. Adopting a display mode of big screen sketch point makes showing the parameters like oxygen concentration, date, time simultaneously possible;
4. Upper and lower alarm limits can be set freely among the whole range;
5. With standard RS232（default）or RS485 communication port, the analyzer can communicate with the computer bidirectionally(optional).
