Description

Instrument Principle

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.

As the smoke builds up in the chamber, the light is obstructed, and the absorption of light increases. The photocell detects this change in light intensity and converts the light into electrical signal. The voltage form the photocell is captured by the PLC and converted into absorption value.

 Standard

The instrument is manufactured as per the IEC 61034 and IS: 10810 (Pt.63) specification.
