SODISTAR - Diffusivity Meter
Sodim has built on its diffusivity meter, which has set standards for measuring the gas diffusion capacity of cigarette paper, to form the SODISTAR. The tobacco industry and paper manufacturers can use it to assess the burning
rate of cigarettes. It offers much more than its predecessor: speed, ease of use, automation and measuring variants.
Quick, automatic and suitable for all kinds of paper. The burning rate of cigarettes can be predicted accurately with SODISTAR's quick, automatic and reliably consistent measurements of the diffusion capacity, or D* for short. The little star inspired the name for SODISTAR. It is suitable for both conventional cigarette papers and printed bands of low-ignition propensity (LIP) paper. What's more, the SODISTAR is quicker and much more compact than its predecessor while featuring an integrated PC. Using it is very easy thanks to the new automatic calibration feature for the analyzer sensor and gas flow together with the automatic paper feed.
Choice of three measuring variants. These modes can also be used to perform correlation analyses of the different methods:
- Laboratory mode: the Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) recommends stopping the measurement of gas diffusion capacity when stability has been reached. This measuring method is
therefore of great significance for most paper and cigarette manufacturers. Since the launch of SODISTAR, Sodim has been the only manufacturer to have met this CRM 77 guideline for all types of paper – including LIP paper. This material often requires measurements of around 25 seconds, on average.
- Production mode: alternatively, SODISTAR offers the possibility of a highspeed measurement lasting 13 seconds. To this end, Sodim complies with the CRM 77 requirements and thanks to improved design and calculations
the stability required to end the measurement is reached more rapidly. This combines speed and accuracy, providing a high measurement cadence and allowing for quick and reliable production checks.„
- Time constant mode: in this third mode the measurement ends either when stability has been reached or after a specified time limit.
