Columbia Research Laboratories (Woodlyn, PA) has introduced the Model VM-300 vibration meter, a general purpose vibration measuring instrument designed for routine checks of industrial equipment where portability and ease of use are required. Acceleration, velocity, and displacement measurement modes are provided, along with a number of value enhancing features. 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. An automatic ten minute timeout during battery operation will not allow the meter to drain the battery while unattended.
