Page 5: Introduction
Introduction The AEROCET 532 is a full–featured, battery operated, handheld particle counter or mass monitor. In count mode, the unit will measure particle counts at eight fixed sizes (0.3 µm, 0.5 µm, 1.0 µm, 2.5 µm, 4.0 µm, 5.0 µm, 7.0 µm, and 10.0 µm). - Page 6 PN 400113 Rubber Boot Carrying Case PN 550537 PN 83549 Figure 1 – Standard Accessories Flow Meter Flow Meter Docking Station PN 9801 PN Swift 6.0 PN 83529 Figure 2 – Optional Accessories AEROCET 532 Manual Rev A Page 6...

The Memory screen allows the user to view available memory or to clear the memory. The AEROCET 532 memory is circular, meaning when the memory is full, the unit will start overwriting the oldest saved samples with new samples. Free shows the percent of space available for data storage. -
Page 18: K-Factors
The individual user k-factors for each mass channel can be set from 0.1 to 20.0. Figure 15 - K-Factor Screen The AEROCET 532 calibration is performed using ideal polystyrene latex (PSL) spheres, which provide a powerful tool for assessing the sensitivity, accuracy, resolution, and false count level. -
Page 19: Flow
Calculate the K-Factor for each particulate size fraction as the reference concentration divided by the AEROCET 532 light scatter concentration over the same time period. For example, if the reference total concentration was 51 μg/m and the AEROCET total concentration was 38 μg/m... -

Page 28: Maintenance
Due to the nature of the instrument, there are minimal customer serviceable components in the AEROCET 532. The case of the AEROCET 532 should never be removed or opened for any reason. Opening or removing the case of the AEROCET 532 voids the warranty and may result in exposure to laser radiation, which can cause eye injury. -
Page 29: Annual Calibration
8.4. Annual Calibration The AEROCET 532 should be sent back to Met One Instruments yearly for calibration and inspection. The annual calibration cannot be performed by the customer because this calibration requires specialized equipment and a skilled technician. Met One Instruments maintains a calibration facility for calibrating particle counters according to industry accepted methods such as ISO and NIST. -
