Automatic Touch Screen Controlled Minimum Oxygen Concentration Tester by ASTM D2863

Introduction:
This Oxygen Concentration Tester measures minimum oxygen concentration as necessary when specimen combustion.
The oxygen sensor is adapted Paramagnetic Type which has a precise, long life, less error rate and high reliability.
The Oxygen Concentration Tester meets the requirements of standards like ASTM D2863, ISO 4589-2, NES714 and so on.

Features:
1. Oxygen sensor, accuracy<0.1%;
2. Touch screen setting of oxygen percentage concentration, automatic adjustment;
3. Digitally display nitrogen flow rate and mixed gas flow rate;
3. One click setting, automatic ratio display of oxygen percentage concentration, without the need for manual adjustment and calculation;
4. High temperature and heat-resistant quartz glass cylinder, capable of withstanding high temperatures during testing;
5. Gas ignition device, with adjustable flame length and the ability to cut off the gas source;
6. Provide sample holders for supportable samples and unsupportable samples;
7. The quartz cylinder can automatically rise or fall, making it easy to replace samples;
8. Gas pipeline optimization design, providing faster response time;
9. The air circuit is a mass flow controller;
10.The controller adopts an imported programmable controller.
11.Adopt imported Paramagnetic oxygen analyzer and Mass flow meter.
