Beta
Gauge Method Particulate Matter SPM-613
|
The SPM-613
particulate monitor utilizes the Beta Gauge Method; beta ray
absorption corresponds to mass weight. A beta gauge measures mass
concentration continuously while sampling aerosol on a rolled tape
filter. The beta ray source (147Pm)
intensity is less than 3.7 MBq (100
uCi), in
the level of which is free from any regulation to
operate.
|
One Hour Measurement
Simultaneous and continuous measurement ( one hour cycle) for
suspended
particles. |
Easy Operation
It is easy to operate the instrument using the well-engineered
interface with the touch screen display. The user is able to set up
using only this touch screen display by pushing the buttons indicated
on the screen. |
Fluorocarbon Filter
By using fluorocarbon membrane filters, the instrument is
less subject to humidity than glass-fiber filters. Therefore,
the measurement accuracy is improved substantially. |
Internet
The data is available to download using the Internet
anywhere in the
world, because the instrument has an IP address. (A PC
with an Ethernet port is necessary.) |
