ROTOMECH India introduce “FAST TRACER" an INNOVATIVE Vibration Analyser with TRIAXIAL Accelerometer sensor - the beauty is that this SENSOR is the product of MEMS technology (Micro Eletro-Mechanical Systems), which never need calibration - this sensor itself is "ANALYSER" with USB connector to the LAPTOP -& thereafter all you need just a software - here you can see the all the data of HORIZONTAL, VERTICAL & AXIAL simultaneously - hence no need to change the direction of sensor to take the reading in three different direction.
