2、 Functional Features

JCY-3 Touchscreen Smoke Density Tester for Building Materials Product Features

1. Building material smoke density tester with added touch screen control technology!The dual control mode of touch screen and computer is optional, allowing for both touch screen control and computer control, with strong logic and high intelligence.

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

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

4. Default touch screen control test, complete the test process with a light touch, and switch to computer control mode autonomously. The computer comes pre installed with software for testing.

3、 Related technical parameters

1. For the z-large smoke density (MSD) and smoke density grade (SDR) of the specimen: 0-100% continuously measurable, automatically calculated;

2. The correction error using standard light filter should not exceed 3%; Each device is equipped with three standard filters, which are representative of the data calibrated by the light source
