6. Optoelectronic system: The light source is a bulb, with a power of 15W and a working voltage of 6V;

7. Exhaust system: This machine is equipped with a powerful exhaust fan, which can discharge exhaust gas outdoors after testing;

8. Smoke density measurement range: 0-100%;

9. Accuracy of smoke density measurement: ± 3%;

10. Receiver: It is a silicon photovoltaic cell, with a transmittance of 0% indicating no light passing through, and a transmittance of 100% indicating no obstruction of light,

11. Working pressure of main burner: 276KPa (adjustable);

12. Automatic timing, automatic ignition, and automatic smoke exhaust; Luminous flux can be linearly calibrated in stages according to test data

More accurate;

4. Gas pressure: 0-0.3MPa (adjustable);

5. Environmental and testing requirements: The instrument should avoid direct exposure or reflection of strong light during operation; After 90 minutes of testing, the gas source should be turned off to cool down the instrument for 15 minutes.

6. Environmental airflow: There is no forced air flow during operation;

7. The instrument should be tested in a fume hood;

FiveSmoke density testerstructure

Divided into two main parts: smoke box and control;

Smoke box section: On the left and right panels of the smoke box, there are power switches, safety sign switches (backlight switches), gas regulating devices, and switches for controlling exhaust fans (fan switches).
