Unique and innovative design features make the Sigma 50 Dynamometer very simple, safe and easy to use. You have full control over the test with the Sigma Hand-held, with its continuous readout of power, speed, torque and torque backup or torque reserve. You can complete a test in minutes. The simple but sophisticated design means there`s no need to warm up the dynamometer or follow regular calibration procedures. Apart from the input shaft, the rotor of the burden alternator and the cooling fans, there are no moving parts in the whole Sigma 50 Dynamometer. This means that reliability is high, and maintenance costs are minimal.
