This research is to develop an installation of non-destructive detection for disorder mango based on responses to slight impact by a simple pendulum with force transducer. A load cell sensor picks the force-time waveforms, of which, the peak force (Fp), the time to peak force (tp), the duration of contact with the sensor (tc), and the impulse of contact with the sensor (J) are definition as basic parameter of impact, and used them to obtain associated parameter of impact. All impact parameters are conduct from the step regression and discriminate analysis. The accuracy of detection for normal and disorder mango is investigated. The results showed that it has significance difference on parameter of impact for normal and disorder mango each other. The correct rate of detection for disorder mango is 86.0% using the characteristic parameter of tc and J from the discriminate analysis. It could be approved that the slight impact test for detecting disorder mango is a non-destructive detection from the repeat slight impact test and the puncture test result.
