Yes, our products are rigorously examined by SGS with useful life (frequency of use is up to 10,000 times), as well as, are examined by the laboratory testing (frequency of use is up to 100,000 times) involving: drop, vibration, high-low temperature testing.
No, the sensor's useful life is up to 20 years, the voltage generated by sensor does not appear change.
Due to different using methods for each user will affect the performance of torque values. With the increasing use of time, the sensor will appear a slight error. To avoid misunderstand of readers, we indicate the error range with CW ±1.5% and CCW ±2.5%.
Yes, our products have an examination report, the used correcting facilities conform the SGS standard (EN ISO 6789:2003)
