Vibration meter
10 - 1 000 Hz | VM-300 Columbia Research Laboratories

The Columbia Model VM-300 Vibration Meter is a general-purpose vibration measuring instrument for periodic routine vibration checks of industrial machinery and general field use where portability and ease of use are required. This hand-held device is the ideal preventive maintenance tool.

Model VM-300 operates from a rugged, precision piezoelectric accelerometer and incorporates a charge amplifier input stage for stability and minimizing errors. Operation is controlled by an internal integrated microcontroller acting under direction of a splash-resistant 7- key membrane keypad.

features:
- An optional printer can be connected to the VM-300 Meter for making permanent records of readings taken.
- Dual power allows the VM-300 to be powered from its internal battery in the field, or from an external AC adapter to save battery life in bench applications.
- A precision low-voltage lockout circuit prevents the VM-300 Meter from making erroneous readings due to low battery.
- Automatic 10-minute timeout during battery operation prevents the VM-300 from draining its battery while untended.
