TK81 | Bently Nevada Tunable Filter/Vibration Meter

Description

The TK81 Tunable Filter/Vibration Meter is a portable, handheld device designed for basic vibration measurements. It offers unfiltered and filtered modes and accepts inputs from displacement, velocity, and acceleration transducers (though it doesn't provide power to them).
