Equipment description:

Full-color touch screen control, only need to set the oxygen concentration value on the touch screen, the program will automatically adjust to the oxygen concentration balance and emit a beeping sound prompt, eliminating the trouble of manually adjusting the oxygen concentration;

The use of a step-by-step proportional valve greatly improves the control accuracy of the flow. The closed-loop control is adopted. During the test, the oxygen concentration drift program is automatically adjusted back to the target value, which avoids the disadvantage that the traditional oxygen index meter cannot adjust the oxygen concentration during the test, and greatly improves Test accuracy.

To meet the standard:

Comply with GB/T2406 “Plastic Flammability Test Method-Oxygen Index Method” and JIS7201, BS2782, ANSI/ASTM, D2863, ISO4589, test standards.

Technical parameters:

Chassis and part of the structure:

1. Control box: It is formed by CNC machine tools, the arc shape is beautiful and generous. The electrostatic paint test is beautiful, and it is anti-rust and anti-corrosion.

2. Combustion tube: high temperature resistant high quality glass tube (inner diameter ￠750mm, length 480mm)

3. Outlet inner diameter: φ40mm

4. Specimen clamp: self-supporting clamp, which can clamp the specimen vertically.

Electric control system:

1. The relay control system is adopted, and all electronic components are adopted domestic leading brands, which can better ensure the performance and detection accuracy of the machine.

2. The equipment has the following safety protection devices: power overload, short circuit protection, and control loop overload protection.
