4 Product Features:

1. Dual control mode, which can be controlled through touch screen or operated on a computer, and the operation mode can be switched freely.

2. One device can be operated by multiple computers simultaneously, multiple computers can be online at the same time, and LAN sharing can be achieved.

3. The main and auxiliary burners can rotate automatically with accurate positioning.

4. Automatic timing, automatic ignition, and automatic smoke exhaust.

5. The luminous flux can be linearly corrected in stages to make the test data more accurate.

6. Independently develop control programs that can meet various operations, recording, real-time curves, and result calculations in experiments.

Five Main technical parameters:

1. For the ultimate smoke density (MSD) and smoke density rating (SDR) of the specimen: 0-100% continuously measurable, automatically calculated

2. Standard filters: Each device is equipped with three standard filters, which are representative of the data calibrated by the light source

3. Calibration error of standard filter: ≤ 3%
