Model 323

The electronic handheld dynamometers of the model series TesT 323 include a force transducer and a process-controlled electronic unit with advanced software under Windows CE. The various functions are adapted to the daily requirements of quality assurance. An integrated data logger with 4 MB, supplemented by an SD card with 2 GB storage space allows, for example, saving peak values ​​or curves in Excel files. Online or after use the data can be transferred to a computer via an USB 2.0 port, for further processing / storage. The files are automatically named uniquely.

A list of options can be found below in the technical data. Basic settings, that had been stored once, even remain when the device has been switched off. After switching it on the device is immediately ready for usage again. The handy case with its ergonomic design is suitable for right and left handers. A fixed mounting in a testing fixture is also possible.

Rechargeable batteries provide a smooth and mobile use for more than 10 hours. These robust devices are suitable for industrial applications and can be recharged overnight. The calibration is carried out with reference instruments or weights, which are in turn calibrated regularly by the PTB or by DAkkS approved bodies. The traceability to ISO 9000 ff is thus guaranteed.

Dynamometer – Model 323

• Capacities: 20N to 5kN
• Integrated force transducer
• Measuring uncertainty: ≤ ±0,05 %
• Measuring frequency: 50Hz – 2kHz, selectable
• 32bit RISC µProcessor

The dynamometers of the model series 323 contain a high-resolution force sensor as well as processor-controlled electronic unit with most modern software. The main areas of application for these devices are quality assurance, incoming goods inspection, production and research and development. Particularly operating forces as well as stability of components will be measured (springs, tracers, switches, levers, fasteners, etc.). The model 323 is used cross-sectorally e.g. in food industry, cosmetics, automotive, or medical technology.
