Lasair III Particle Counter for spot checking or continuous monitoring

Printable Version

Which particles counters should I use for spot checking versus continuous monitoring?

Spot Checks

• The Handilaz Mini handheld particle counteror Lasair III portable particle counters are best suited for spot checks.
• The HandiLaz is a small, handheld particle counter with sensitivity at 0.3 µm and sampling rate of 0.1 CFM.
• The Lasair III particle counters are lightweight, portable devices with sensitivity at 0.3 and 0.5 µm and sampling rates of 100 LPM, 50 LPM or 1 CFM. The Lasair III particle counters provide six particle channels and more extensive data analysis features than the HandiLaz series.

Continuous Monitoring

• The Airnet, Lasair III, or IsoAir series particle countesr are ideal for continuous monitoring.
• The Airnet particle sensors are small units, with 2 or 4 channels, and since they do not include a display, they must report data to a network facility monitoring system.
• The Lasair III particle counters are lightweight, with 6 channels, and since they include a display, can be used in standalone mode and report data to a network facility monitoring system.
• The IsoAir particle countesr are designed within a rugged, chemically-resistant stainless steel case for environments that may be more harsh than a typical cleanroom. They include 4 or 6 channels (depending on the model), and since they do not include a display, they must report data to a network facility monitoring system.
