Operational & Practical Notes / Behavior
The 3313LL counts particles by passing a laser (or light source) through the sampled air stream; when particles pass through the beam, they scatter light, which is detected by a photodetector.
By having multiple size channels, the instrument can bin the counts into different particle-size ranges (for example: 0.3 µm, 0.5 µm, 1.0 µm, 3.0 µm, 5.0 µm, 10.0 µm).

It likely offers programmable sampling intervals, hold times, alarm thresholds, etc. (common features in Met One/Met One‑type instruments).
Data export via serial is standard, allowing integration with control or data acquisition systems.
Because it’s a relatively high‑flow device (1 CFM), it can sample a substantial volume of air (improving statistical confidence in counts).
The stainless steel construction helps with durability, cleanliness, and possibly resistance to corrosion or harsh environments.
As a used / legacy device, calibration, maintenance, and replacement parts (filters, laser, pump, optics) may be important considerations.
