Smoke Density Test Apparatus - China

scope of application

the touch screen computer dual control smoke density tester for building materials is developed according to the technical conditions specified in the national standard gb / t8627-2007 "test method for smoke density of burning or decomposition of building materials".

it is suitable for the determination of static smoke yield of building materials and their products and other materials.

product features

1 - dual control mode, which can be controlled on the touch screen or the computer, and the operation mode can be easily switched! (user's computer and printer; upper computer software, router, and network cable will be sent with the device)

2 - a device can be operated by several computers at the same time, and several computers can be online at the same time, which can realize lan sharing!

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

4 - the self-developed control program can meet the requirements of various operations, records, time curves, and results calculation in the test.

technical parameter

1 - the maximum smoke density (msd) and smoke density rating (sdr) of the specimen are 0-100% continuously measurable and automatically calculated;

2 - the calibration error of the standard filter is not more than 3%; each equipment is equipped with three standard filters, which are representative of the data of light source calibration

3 - the working pressure of the bunsen lamp was (210 ± 5) kpa;

4 - benson lamp applied flame to the sample for 4 min;

5 - combustion lamp: bunsen lamp, length 260mm, nozzle diameter 0.13mm, 45 ° angle with smoke box;

6 - photoelectric system: the light source is a bulb, power is 15w, working voltage is 6v;

instrument structure

it is divided into the smoke box and a control system;

smokebox: on the left and right panels of the smoke box, there is a power switch, safety sign switch (backlight switch), gas regulating device, and switch for controlling the exhaust fan (fan switch).
