MIL812

High Temperature Vibration Meter (Gas Turbine)
Part Number M12251

The Mechanalysis model MIL812 is a small lightweight and easy to use portable digital vibration meter designed for high temperature portable vibration measurements with special applications to Gas Turbines. The meter has a clear digital auto ranging display. Hand held the meter measures machinery vibration in terms of, velocity (mm/sec) and acceleration (g) in accordance with ISO2372. It also features a built-in transducer integrity check facility.

All functions are available on the front keypad. The MIL566 accelerometer is suitable for measuring up to 5000C with and in line charge amplifier, it offers overall vibration measurement in a harsh environment.
