The NGK range of dynamometers have been the standard unit for accurate tensioning of conductors within the UK overhead line industry for many years. The range is both compact and lightweight (110mm in length and 65mm in diameter, weighing only 0.7kg on DYNO04) with a clear and easy to read dial face. The DYNO04 model has a eye opening of 11mm in diameter. They units are calibrated to give an accuracy within 3%. Each dynamometer is supplied in a heavy duty protective leather storage case.
