Trek's Model 212HS Charge-to-Mass Ratio System 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.
* Measuring toner mass requires the use of a weigh scale which is not included in the Charge-to-Mass Ratio Test System.
