Who makes Portacount?
Professionals in Occupational Health & Safety, Industrial Hygiene, Emergency Response, and Healthcare have relied on TSI’s PortaCount respirator fit testing products since 1987. We support worker safety initiatives and programs with the most accurate quantitative respirator fit testing systems available.
How much does a Portacount cost?
The PortaCount® Pro+ Respirator Fit Tester 8038 eliminates the guesswork associated with tedious and error-prone qualitative fit test methods….Equipment Condition: New.
How does Portacount fit testing work?
It uses the microscopic particles that exist in ambient air to measure the fit factor directly. The PORTACOUNT measures the concentration of these par- ticles around the person’s head and then measures the concentration of those particles that leak into the respirator. The ratio of these two numbers is the fit factor.
What is the difference between qualitative and quantitative fit testing?
The main difference between quantitative mask fit testing and qualitative mask fit testing is that quantitative testing objectively measures the amount of leakage (quantity) while qualitative testing relies subjectively on the users taste and smell to detect leakage.
What is a N95 companion?
N95-Companion™ Technology TSI’s N95-Companion uses an electro-mechanical method to challenge a mask with particles only in the range that will challenge the face seal and not the filter. For most filters, the Most Penetrating Particle Size (MPPS) is in the 200 to 400 nanometer (nm) range.
When performing a positive pressure test what indicates proper respirator fit?
To conduct a positive pressure check, follow this procedure: Don the facepiece and adjust so it’s snug but not overly tight. Using the palm of your hand, block the exhalation valve, usually found on the bottom of the respirator. Gently try to breathe out, which should allow the facepiece to puff out slightly.
How long does a Portacount test take?
Set up PortaCount® machine and run daily check, making sure ambient particle count is over 3000 pcm3 for testing half-face respirators and is over 10000 pcm3 for full-face respirators. 60 minutes or eaten in the last 15 minutes.
How does a Portacount work?
The Portacount works by measuring the concentration of microscopic dust particles in the ambient air and then measuring the concentration of those dust particles that leak into the respirator. The ratio of these two concentrations is called the fit factor.
