  • Which digital photometer is best for testing HEPA filters?
  • The Rigel RI7001 digital photometer is the best choice for testing the integrity of HEPA filters. Using the light scattering method, the Rigel RI7001 provides real-time integrity through detection of aerosol concentration upstream and downstream.
  • What aerosols are used for HEPA testing?
  • Polystyrene latex (PSL) spheres are most commonly used in microelectronic applications, while polyalphaolefin (PAO) in life sciences. The information in Table 1 describes the typical challenge aerosols used for HEPA testing. Before starting the filter scan, it is necessary to set the concentration of test aerosol particles upstream of the filter.
  • How accurate is an aerosol photometry test?
  • The traditional aerosol photometry test method, used since the 1950s, is adequate for measurements to 0.003% by DOP scan testing. To perform an accurate filter leak test, it is necessary to make sure the challenge aerosol concentration is uniform over the entire upstream face of the filter (s) being tested; this is called spatial uniformity.
  • How do you test a DOP / Pao filter?
  • The DOP / PAO aerosol mixture is introduced at the suction, mixed in the unit, and then passes through the filter. Step 7 The scanning test is performed using the hand held scanning probe. The entire exhaust area of the equipment is sampled by passing the probe in overlapping strokes across the face and perimeter of the exhaust.
  • Who sells aerosol generators & ATI photometers?
  • CMI sells and rents aerosol generators and portable ATI (Air Techniques International) photometers designed for many applications in the pharmaceutical, biotechnology, healthcare, nuclear and dismantling industries as well as for use by professionals working with asbestos and asbestos removal.
  • What is DOP/Pao testing?
  • This document has been designed to address the Ontario Hazardous Materials Abatement industry standards regarding DOP/PAO Testing of HEPA filtered negative air units, vacuums and any other HEPA filtered equipment used on-site to control hazardous particulate during abatement, remediation and construction projects.
