The 500 series portable sample chiller is a staple to the mobile stack testing and laboratory setting. In order to analyze stack gas or exhaust from any combustion process, a method to remove moisture from the sample without removing gas components of interest is a must. The Universal Analyzers Thermoelectric Sample Cooler, which derives its cooling from the Peltier Effect, is an ideal way to decrease the dew point of combustion gasses to a low dew point. For gas analyzers where water vapor interferes with the reading, a stable, repeatable, low dew point becomes a part of the gas analyzer’s performance specification. The Universal Analyzer Gas Sample Coolers prevent water condensation in sample pre-filters, sample pumps, and gas analyzers. The Universal Analyzers sample cooler provides this constant water concentration resulting in an accurate analysis of the components of interest.
