Trek's Charge-to-Mass Ratio System (Model 212HS) is a portable
Q/m analyzer that utilizes the “draw-off” toner transfer method
to provide repeatable, highly accurate toner/powder charge
measurements. Due to its small size and weight, the instrument
is highly portable, making it an excellent choice for use directly
on the production line or in the laboratory.
The TREK Model 212HS system employs a unique specimen
separation and transfer technique that avoids the creation of
measurement errors due to the undesired additional charging of
test specimens sometimes caused by the rapid air movement
associated with "blow-off" type measurement systems. The unit
is configured as a separate main indicator unit, a plug-in sample
cell unit, and a plug-in absorption nozzle unit to allow for different
configurations in response to various user applications. A two
position switch selects pump strength for normal or high
application needs, such as for measuring charge on single
component toners (when stronger suction is required).
All measurement data is displayed on a front panel read-out and
is available as analog voltage data on output 1 (absorption
nozzle data) and output 2 (sample cell data) rear panel BNC
connectors. Data can be temporarily stored to on-board system
memory with the push of a button and then saved more
permanently to a personal computer.
NOTE: Measuring toner/powder mass requires the use of a weigh
scale which is not included with this Charge-to-Mass Ratio Test
System.
