In the past, if you wanted six size channels or printer capabilities, you had to contend
with a large, heavy counter or with external printers, cables, and cords. Now Met One
gives you battery-operated portability, up to six size channels, and a built-in printer
all in one compact instrument!
The 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. 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 results you can immediately print or download later
using Particle Vision PortAll Software. The bright LED display lets you see the
data easily. The Model 237: bright display, printer and cordless operation a real asset
