The testing and development work resulted in new versions of TSI's Automated Filter Testers that can be used for testing to the European EN 143 test standard. The TSI Automated Filter Testers models 8127-1-EN (paraffin oil only) and 8130-1-EN (paraffin oil and NaCl) are now available. Oil and salt aerosol generators for EN equivalent testing are also available to upgrade existing testers. It is now, for the first time, possible to do testing according to European and US standards, with both oil and salt, all in one machine.
