Our Heat and Environment-friendly Equipment test station has a new testing device for measuring of dust particles in the dilution tunnel for EPA certification.
It is a set of three separately usable measuring apparatuses, which was constructed by SZU staff. The instrument was reviewed directly by the EPA auditor and its final version has been improved over the original concept. Two devices are used to collect dust particles from the measuring section. A third apparatus is used to collect samples from the ambient air in order to avoid possible influence of the results in the case of higher dustiness in the surroundings. The devices are interconnected and they are automatically switched on and off at the same time using the software also developed by an employee of the SZU.
The device can also be used to measure the tightness of stoves according to ČSN EN 16510-1.
