Instrument characteristics

1. The combustion cylinder with a heating element and a preheater. the temperature ofcombustioncylinderAdjustable .

2. The computerautomatically  controlsthe entiretest  process. The operator inputs the oxygen concentrationvalue  fromthe keyboard based on the test requirements. The instrument can automatically adjust the oxygen concentration value in the rangeof  setting.

3. Direct detection and display of oxygen concentration value in the sample chamber.

4. Automatic ignition is safe andreliable .

5. The computer automatically handles each set of testdata,and the determining reliability of the testdata  .
