Description

 

Smoke Density Apparatus is used for measuring & observing the relative amount (Density) of smoke produced by the burning (combustion) or decomposition of Plastic, Cables etc. under controlled conditions.

 

The sample is burned under controlled conditions by alcohol fire. A light source and a photo receptor is placed on either side of the chamber, and the percentage of light absorbed is displayed through a linear amplifier digital electronic photometer with 0 to 100% absorbance scale.

 

The instrument is manufactured as per the IECspecification and also confirms various other international standards. The instrument comprising of       
 

 

    A Double walled 3m x 3m 3 m Chamber (powder Coated for long life).  

    PLC Based control System for Standardized DC Voltage, Light Source, Photo Receptor, Mixing Fan, Exhaust Fan

    Touch Screen HMI for Controls and Display
    Display of Test Progress on Data / Graphical Screen

    Display of Results with all parameters and final Standard / measured absorption.    

   The Chamber is constructed on Aluminum Columns and 2mm thick GI Sheets. This ensure no rust formation on the chamber
    Door to access the chamber from inside with glass window
    Alcohol Tray as per specifications
    Sample Stand
    Mixing fan inside the chamber along with Sheet shielding as per specifications
    Constant DC power supply to produce 12 V DC for the light source
    Light source 12 V DC to form light spot of 1.5m dia on the photometric system wall.
    Electronic Photometric System to capture and display the % Transmission of light. Consist of Photo Cell and Receptor
    Specially developed Software to capture % transmission from the photometric system. After the test the results can be displayed in tabular / graph form
