Quatek - Model 212HS -Charge-to-Mass Ratio Test System
The Model 212HS Q/m Analyzer stands out as a highly portable and precise instrument for measuring the charge-to-mass ratio of toners and powders. Utilizing a unique specimen separation and transfer technique, it avoids common measurement errors associated with traditional `blow-off` methods. This system is especially beneficial for on-the-fly production line testing or laboratory use due to its manageable size and weight. The unit comprises a main indicator unit, plug-in sample cell unit, and plug-in absorption nozzle unit, which enable versatile applications. The analyzer features a two-position switch for pump strength adjustment to cater to various needs, particularly for single-component toners requiring stronger suction. Measurement data is conveniently displayed on the front panel and can be outputted via analog voltage data or stored temporarily in system memory with the press of a button.
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 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.
