Scope of application:
Touch-screen computer dual control smoke density tester for building materials was developed according to the technical conditions stipulated in GB/ t8627-2007 "test methods for smoke density of burning or decomposition of building materials", which is applicable to the measurement of static smoke production from burning of building materials, products and other materials.

ASTM D2843 Smoke Density Tester Smoke Density Measurement Testing Machine For Building Materials GA-9006
Product features
1. Dual control mode, can control the operation on the touch screen, can also be controlled on the computer, the operation mode can be arbitrarily switched!
2. A device can operate several computers at the same time, several computers can be online at the same time, and LAN sharing can be realized!
3. The main and auxiliary burners can rotate automatically and locate accurately. 
4. Independently developed the control program, which can meet all kinds of operations, records, real-time curves and results calculation in the test. 

Relevant technical parameters
1. For the maximum smoke density (MSD) and smoke density grade (SDR) of the specimen: 0-100% continuously measurable and automatically calculated; 
2. Calibration error with standard filter shall not be more than 3%;Each device is equipped with three standard filters, which are representative of the data of light source calibration
3. Working pressure of Bunsen burner (210 + 5) KPa;
