IMV VM-1970 Vibration measuring VM-1970 is the wide band digital charge vibration meter which covers frequency 1Hz to 100kHz. All setting is interactive by the menu selection on the screen. Conversion of measuring value and change of unit is automatic. So it is free from troublesome operation and easy to reading.

■Features

Display of measuring condition and decimal point of measured value and automatic conversion of units for quick data reading H-function is measurable for convenience of detecting bearing deterioration Alarm function is provided(Alarm contact output is option) Measurement of vibration severity in accordance with ISO-10816 Frequency range of 1Hz ～ 100kHz Automatic data processing with GP-IB (option)
