Q: How is the HandiLaz Mini used?
A: The counter can be taken anywhere in the laboratory as it has rechargeable batteries. Simply hold or place it in the test environment and turn it on. The HandiLaz Mini samples the air for a user-defined time, counting the particles within three size ranges (0.3µm, 0.5µm and 5µm). At the end of the test, the results are displayed on the screen in units that can be immediately compared with pass and fail criteria given in the ISO or EU GGMP standards.
Q: How does the HandiLaz Mini work?
A: Air is drawn through the detection chamber by a pump. A laser beam is directed across the chamber and any particles contained in the air reflect the light, appearing as a bright flash. The larger the particle, the brighter the flash. A photo detector measures the brightness of each flash and the meter counts and sorts them into the three size ranges. The software then calculates the results.
Q: What do the numbers on the display mean?
A: They are the particle count per m³ of three particle sizes. We recommend the units are set to counts per m³.
