China Digital Portable Vibration Meter

EMT220 vibration meter has many advantages compared with other vibration meter.
Vibration transducer:
Integral, annular shear type acceleration transducer (only for integral type)Separate, built-in electric charge amplifier, shear type acceleration transducer (only for separate type)
Temperature transducer:
Type K thermoelectro couple transducer (only for EMT220 with temperature measuring function)
Detector:
Root Mean Square
Vibration measurement scale:
