Smoke optical density measurement

Smoke optical density measurement device consists of modulated light source, synchronous light detector and a control unit. The device measures intensity of light travelling from light source into the detector. Thanks to the synchronization of light source and light detector (system works as lock-in amplifier) the device is, to some extent, immune to ambient light and thus might be operated under normal daylight conditions.

As standard the light source is fitted with halogen lamp and the detector uses Si PIN diode with human eye sensitivity correction filter. The light beam is collimated with diameter of 2.54mm (1"). This configuration conforms to most testing standards. On request different types of light sources and detectors could be used.

Fotometer 2008 STD

Basic model for smoke optical density measurement. Light source and light detector are designed for installation outside the test chamber in normal environment. Windows must be provided on test chamber so the light beam can pass through.

Fotometer 2008 COOL

This model's light source and light detector might be installed directly into the testing chamber. They are equipped with water cooling jacket and their design is robust enough to withstand harsh environment inside the chamber including tepmperatures up to 150 degrees celsius. The input windows have air-purge units which prevent any dust from spoiling the window. The device requires connections to water supply for cooling and pressured air for air purging of windows.

Custom design

In case that none of the standard devices fits your needs we can modify the design for you so it complies with your requirements or the ISO testing standard you need.
