Vasthi uses heated probe to collect the sample from the sample line, it will maintain constant temperature and removes the dust and mist from the sample gas. This gas sample passes through electrically heated tube to cooler. It will remove the vapour content and cools the gas sample to 5ᵒC dew point range and this sample gas goes through the filter that eliminates the dust particle remaining and finally sensor senses and gives the exact readings in syngas analyzer.
