• DMA Dynamometers are tensile load cells with an internal display designed by Kobastar for use in force measurement.
• It is manufactured from special alloyed high strength aluminium materials used in the aviation industry.
• The body surface is hard anodised to make it more resistant to harsh environmental conditions.
• In addition to wired models with analogue and digital outputs, there are versions with built-in display and wireless communication with external hand terminal.
• The wireless model can be controlled and controlled from the hand terminal.
  Thanks to its robust and rigid structure, it makes precise measurements with an accuracy of 0.1%.
• It works for 80 hours continuously with the built-in rechargeable battery.
• The force measurement units commonly used in the world are kilogram (kg), tonne (t) pound (lb), newton (N) and kilonewton (kN).
• 16 DMA single hand indicators can be used to monitor individual and/or total weight.
• Produced in Kobastar factories in different capacities from 3 tonnes to 500 tonnes.
