Portable Airborne Particle Counters

The Portable Airborne Particle Counters Model 237 counts airborne particles in up to six different size ranges simultaneously. Count data is displayed on the front-panel as total number of particles (cumulative count) or the particles in each size range (differential count). The printout shows cumulative and differential count data for each size range. For maximum flexibility, four modes have been incorporated to provide quick answers to measurement questions or to allow unattended operation. The manual mode completes one count cycle then turns the air pump off to prolong battery life. Auto mode repeats the count cycle for the number of cycles programmed to allow unattended monitoring. The concentration mode gives a quick estimate (within seconds) of the particle concentration. Beep mode provides one beep after the count exceeds a selected limit, which is handy for isolating sources of particle contamination such as leaks in filter banks. Now it is easy to carry a particle counter right to the point of interest and obtain quick, accurate results can immediately print or download later using Particle Vision Port All Software. The bright LED display lets you see the data easily. It has bright display, printer and cordless operation a real asset in any clean room.
