This operating guide describes how to use both the Model A2100C and A2200C Particle Counters, both of which operate identically. This operating guide provides complete operating, application, and maintenance information for the particle counter. Any changes of instrument operation due to design changes are covered at the back of this guide in the “Manual Backdating” section.
Both particle counters have six particle-size channels. The Model 2100C counts particles as small as 0.1 micron. The Model 2200C counts particles down to 0.16(special) or 0.2 micron (standard). Specify size at time of order. A built-in printer is standard. A microprocessor controls all instrument functions. Count data is displayed as cumulative count or differential count. Refer to Specifications in this manual for a complete listing of available size channels.
The particle counter uses a helium-neon (HeNe) light source and collection optics for particle detection. Particles scatter light from the light source. The collection optics focus the light onto a photo diode that converts the bursts of light into electrical pulses. The pulse height is proportional to the particle size. Pulses are counted and their amplitude is measured for particle sizing. Results are displayed as particle counts in the specified size channel.
