Biological Detectors

Detection method & sensitivity
Look at the technology used (UV fluorescence, laser scattering + fluorescence, mass‑spectrometry, immunoassay) and how many particles per liter air it can detect.
For example BM3001 lists sensitivity: ≤ 3 ACPLA (agent‑classified particles per liter) for bacteria, spores, viruses.

Particle size & sampling rate
The device should cover the respirable size range of bio‑aerosols (often ~0.5‑10 µm or more) and have a sufficient air flow to sample a meaningful volume. Eg BM3001 covers 0.5‑10 µm.

Response time & alarm capability
How quickly does the detector trigger an alert upon detecting elevated biological particles? Some models aim for seconds or a few minutes. Eg BioFlyte’s system claims “in just 5 minutes” detection + identification of airborne hazards.

Consumables/maintenance & uptime
Some systems require regular filters, assay kits or other consumables; others are designed to operate continuously with minimal consumables. For example the FLIR IBAC 2 is described as “autonomous 24/7 operation with no consumables”.

Data output, networking & integration
For use in facilities or security settings, check how the device connects (Ethernet, RS‑232/485, wireless), whether it can hook into building management or security systems, and how alarms are delivered. Eg the BERTIN ENVI BioScout supports Ethernet, RS‑232/485 and relay output.

Environment & application suitability
Consider if you need indoor only, outdoor/hardened, mobile or fixed installation. Check temperature/humidity range, ruggedness, mounting options, whether fit for critical infrastructure, transportation hubs, etc. Eg ENVI BioScout has a rugged version for naval vessels, armoured vehicles.
