•
Relative Humidity: 10% to 80% without condensation
• Altitude: Up to 2000 m (5500 ft). Above 7300 m (20,000 ft) unpressurized transport may damage
the monitor.
• Electrolyte Solutions: All aqueous and non-aqueous electrolyte solutions devised for use with
aperture technology are suitable for use with the Multisizer 4. Electrolytes should be
compatible with glass, fluoropolymers, fluoroelastomers, and stainless steel.

NOTE
The upper size limit is dictated by solution viscosity and particle density, and the lower limit by
the aperture size, solution conductivity, and environmental conditions.

• Number of channels: Pulse data is stored in unchannelized form and can displayed in up to 400
size classes for any selected size range. The number of channels and their range can be
reprocessed as necessary.
•
Digital pulse processor: High-speed digitalization of the signal allows the definition of pulses by
a number of characteristics. This information may be used at a later time to recalculate the size
distribution using different pulse parameters.
• Pulse data: Up to 525,000 pulses per analysis
•
Linearity for 2% to 60% of aperture diameter (10% to 80% of aperture diameter for a 2000-µm aperture):
± 1% for diameter, ± 3% for volume
•
Aperture tube sizes: 20-µm to 2000-µm apertures (nominal sizes). Each size allows the
measurement of particles in a range of 2% to 80% of aperture diameter, except the 2000-µm
aperture, which is capable of 10% to 80% of aperture diameter.
