The handheld N330 is our latest dual-channel, portable balancing vibrometer and machine analyser. As a handheld device it is designed to enable engineers to identify vibration issues in the most convenient manner and pursue a proactive, preventative maintenance routine to limit production downtime and extend machine life.

Applicable across multiple sectors and applications, the N330 is intuitive to use and allows engineers to identify any balancing issues quickly onsite. While in use, the N330 displays the balance values and a menu button provides the option to save over 1000+ readings, thanks to 14.8GB of space that can be expended to 128GB.

The device is capable of both single and two-plane balancing as well as FFT, Smart Analysis, Vibrometer and Tachometer.
