Technical indicators and working conditions of digital oxygen index analyzer

The Digital Oxygen Index Tester is a new type of flame retardant testing equipment used to test the concentration of oxygen (percentage of oxygen) required during the combustion of a polymer. The oxygen index of the polymer is after the substance is ignited. The volume percentage concentration of the lowest oxygen in the oxygen-nitrogen mixed gas required to maintain a combustion of 50 mm or a combustion time of 3 minutes. The following is a brief introduction to the technical specifications and working conditions of the digital oxygen index meter.

Technical indicators of the digital oxygen index tester:

1. Voltage regulation accuracy: ≤0.003Mpa;

2. Flow stability: ≤0.003Mpa;

3. Response time: <10 seconds;
