Monitoring of 365nm UV-stimulated particle scattering and biofluorescence using photon counting electro-optics. Alarm decisions are based on algorithms that consider bioaerosol statistical behavior, bio-fluorescence intensity and particle size.
Particle size range
0.5 to 15 microns in four size ranges. Respirable aerosolized bacteria, spores, viruses, and toxins. Biofluorescence intensity in each size range is monitored and reported.
Interferent resistant to diesel smoke, pollen, silica dust.
100 ACPLA in most natural environments, 20-30 ACPLA under laboratory test conditions.
1.2 liter per min of ambient air nominal.
Time to alarm
15 second average, 30 seconds maximum. 15-minute trailing history is used in alarm protocols.
Red LED and >100dB piezoacoustic alarm, plus serial link digital alarm output.
RS-232 or wireless BioLink; pre-programmed for use with sampler.
Serial data output
Alarm, particles per liter of air in each size bin; percentage of particles that are biological; relative biofluorescence compared to scattering intensity for each size bin.
Essentially unlimited if powered externally, or 24+ hours on UBI 2590 rechargeable battery.
Air pump: 30,000 – 40,000 hours. UV light source: greater than 20,000 hours.
Operating temperature range
-40°C to 50°C. Operation to 60°C is permitted up to a total time of 1,000 hours.
0 to 95% non-condensing
Less than 6 watts at 18 VDC to 36 VDC. Uses BA-5590 primary battery or UBI 2590 rechargeable battery. AC mains or vehicle power can be used with proper converter.
