2. LASER PHOTOMETER MODEL 858 A A COMPACT RELIABLE PHOTOMETER FOR CUSTO ED FILTER TESTING A simple command set can be incorporated into your LabVIEW program to give you complete flexibility in test protocol and database management All of these features combine to make the 8587A ideally suited for custom filter testing applications Applications Respirator certification testing fit testing Efficiency testing of HEPA filter assemblies Respirator design and development Filter design and development Aerosol laboratory research TSE UNDERSTANDING ACCELERATED Features and Benefits Same photometer engine as used by NIOSH Filter efficiency measurements to 99 999 Penetration versus particle size to 0 001 Fit factors to 100 Indicates low airfl 000 ow conditions Signal correlates with aerosol mass concentration Stable 30 mW laser light source Internal valve swi downstream sam itches between upstream and ples Automatic gain selection Analog and digital output Manual or remote control via RS 232 or USB Critical orifice controls sample airflow Plug and play compatibility with the original 8587 command language Background In 1990 TSI began developing an advanced technology light scattering photometer to replace aging instruments incapable of measuring the high protection factors p
3. eration The Model 8587A has a simple front panel keypad for manually switching between upstream sampling purging and downstream sampling It also has a digital photometer voltage display on the front panel with the real time analog voltage available via a back panel connector Most users will want to take advantage of the remote control features that allow precise test protocol control via an RS 232 or USB 1 1 interface You can write your own software to control all aspects of testing including sampling mode i e upstream purge downstream read voltage reset voltage query valve status and to control all three valves individually Example program code is included to help programmers get started using the simple ASCII command set Sheath air Low Maintenance The optics are protected by filtered sheath air Aerosols never come in contact with the lenses Filter Testing The Model 8587A is perfect for testing the efficiency of particulate filters In fact the 8587A photometer engine is the same one used in the TSI Automated Filter Tester Model 8130 currently employed by NIOSH for 42CFR part 84 particulate filter certification Integrated valves make switching between upstream purge and downstream measurements simple using front panel or remote control Laboratory Applications The 8587A is useful for a variety of aerosol research applications It is abasic photometer with switching valves added to accommodate easy aerosol concentra
