4-4 Lasair® Pro Aerosol Particle Counter Operations Manual
Power
CAUTION
Fluctuations in the AC Main supply voltage should not exceed +10% of the rated
voltage range.
The Lasair Pro is rated at 19 VDC (150 W) and can be operated with the AC to DC power
adapter or internal batteries. When using AC, the external power supply requires 100-240
V, 50/60 Hz AC power to produce 19 VDC.
Batteries
Insert one or two lithium battery packs into the particle counter for portable operation.
Charge internally before first use.
Optional lithium ion batteries and battery chargers are available from Particle Measuring
Systems.
• Lithium Ion Battery – P/N 1000025008
• Battery Charger with one (1) bay, 115 V – P/N 90101118-10
• Battery Charger with one (1) bay, 230 V – P/N 90101118-20
• Battery Charger with four (4) bays, 115 V – P/N 90101119-10
• Battery Charger with four (4) bays, 230 V – P/N 90101119-20
For a 1 CFM unit, a single battery runs for approximately three hours, and dual (using two)
batteries run for approximately six hours based on continuous sampling and printing
every minute. Battery run and charging times vary with conditions, such as tube length,
sample time, and use of the built-in thermal printer. All battery chargers are CE-compliant.
WARNING
Ensure battery packs are not exposed to vaporized hydrogen peroxide (VHP).
