Portable purity oxygen analyzer adopts the imported limiting current sensor as the measured unit, with a rapid response speed and long calibration cycle for features, etc. With the function of sensor protection, the instrument can be turned on under any circumstances without affecting the sensor's serving life. The built-in sensor temperature-compensation circuit could avoid the influence from temperature change on the measured accuracy.
Portable purity oxygen analyzer main features:
1. Power is supplied by large-capacity lithium battery, with the continuous measuring time more than 24 hoursand the standby time more than 168 hours;
2. Altitude measurement module can be expanded to avoid the influence from atmosphere pressure change on the measured accuracy;
3. With the functions of built-in compensation and sensor protection, the analyzer can be on power under 99.99%condition without affecting the sensor’s serving life;
4. Function of storing data automatically allows users to look through historic data at any time;
5. The measured accuracy of the whole measurement range can be met by a random point calibrated, making the calibration simple and convenient;
6. Sampling pump built in (optional).
