Check Your Rotating Machinery

Portamonitor® is a pocket size condition indicator tool which employs powerful monitoring techniques to analyze the health state of rotating machinery especially with regards to the health and lubrication of bearings With its magnetic sensor head the Portamonitor® can be attached to machineries outer casing and takes readings over a short period to assess the condition of the moving parts within. An overall noise decibel (dB) level is returned along with a distress level after measurement that can then be quickly analyzed and compared to other readings in order to discover if preventative maintenance is required. Hardy and robust, the Portamonitor – ultrasonic bearing indicator can take 1000 readings between charges, which is done through a standard USB lead for easy charging anywhere.
