Click to download Product Catalogue 


19i is probably the most powerful weighing indicator of similar price level. 10,000e OIML Class III approval certificate proves further that it is one of the world’s most accurate class III weighing instruments.


Dual weighing range and interval, plus many other approved functions make 19i the perfect answer for trade and non-trade applications.


Extremely low (0,75μV) input per verification scale interval means 19i is also good for high dead load and at the same time low load cell utilization applications.


19i is designed and programmed to provide fast, easy and straightforward operation to meet an extraordinary wide range of applications like general static & dynamic industrial weighing, piece counting, shipping control, truck & tank weighing, pre-packing, manual sorting & packing, filling & dispensing, scientific & peak measuring & monitoring… etc. no matter as a standalone unit or incorporated in an integrated weighing system.


Thanks to the built-in high speed micro-processor, unsurpassed innovative program, new linearity compensation method, wide range of flexible,selectable operation parameters and selectable AD conversion speed, 19i always deliver unexceptional fast, accurate and stable results from low to high resolution, simple to complicated applications even at extremely heavy workload.


Reliability and durability are safeguarded and guaranteed by the carefully selected components from renowned manufacturers as well as smart designed and well planned circuits.


19i always deliver more than it is expected and the #1 choice whenever & wherever performance, reliability, durability and flexibility are of no compromise.
