The 795M is an economical portable single channel multi-function data collector and FFT spectrum analyzer. It is versatile for overall values measurement, bearing condition diagnostic, spectrum diagnosis and in-situ-multi-plane balancing of rotating machinery (up to 8 planes of correction, up to 16 points to check vibration).
It is a simple and useful device that allows for easy condition monitoring and unbalance correction of any rotating equipment found almost in every process industries. With the Windows based program ConSpect software, it creates an easy to use, cost effective, scalable solution that meets the needs of the novice as well as advanced user. The small, rugged, and light weight IP 65 design makes it ideal for any harsh industrial environments. |
