Product Description

Introduction

The test method of the NBS smoke density chamber is derived from the American National Institute of Standards and Technology NIST (the predecessor of NBS). It has been promoted and applied in many test fields. The test method can be used to test smoke density grade of plastic products, non-metal rail transit materials, ship non-metallic materials, wire and cable products, etc..According to this test method, generally applicable standards are ASTM E662, ISO 5659-2 and the NES 711 smoke density test method.
Compared to building material smoke density test method,this test standard has more accurate test results, and the optical sensor uses a more sophisticated photomultiplier tube, which can capture the subtle changes in the smoke content in the chamber.If you choose other test devices, such as Dräger gas detection tube,it can carry out aviation standard smoke toxicity test, and it can be connected with the FTIR Fourier transform infrared device to complete the qualitative and quantitative analysis of smoke content. 

 

 

Structure of Chamber

1, The NBS Smoke Density Tester is consist of cabinet, sample case, the radiation cone, ignition, light and measuring devices and other relevant control device component;
2, The structural design and control design considers the ergonomics; The test box is designed with full door design approach; lock design for easy one-time close the door; optimize operational processes;
3, The smoke density equipment has fully opened door for easy loading and unloading of samples and cleaning the box;
4, The front door hinge installation with Windows and window has block the activity window opaque visor to prevent light from entering the sealed box;
, The controller is located in the side of the box, easy to operate. When the door is closed,it does not affect the view controller;
6, Security flameout board is simple to replace with safer operation;
7, The smoke density test box is easy cleaning and coating chemical resistance.
 

Combustion System
1, The heating cone: Power 2600W, input temperature range of 0 ~ 1000 ºC, can be stable within ± 2 ºC within 50 minutes, providing irradiance 10KW / m²-50KW / m².
2, The use of mass flow controllers and differential pressure sensor can improve the accuracy of piezometers and automatic leak test.
3, Ignition with automatic ignition devices; flame length 30mm±5mm; in accordance with standards prescribed blue flame with a yellow tip.

Smoke density measurement system
1, Smoke density and temperature are digital display, viewing more convenient, more accurate values.
2, Photodetector assembly includes a photomultiplier, amplified filters, shutters, filters, neutral density filter, a lens, an optical window, and other components.
3, The light source is 6.5V incandescent light sources.
4, The installation of optical cartridge box at the top, light accepted as side-on photomultiplier, light transmission rate of 0.001% accuracy can be achieved.
5, Achromatic lens is provided with ASTM E662 Smoke density test equipment.
6, ISO 5659-2 Smoke Box adopts Japan imported Photomultiplier tubes.
7, High-gain low-noise amplifier control circuit.
