Hand-Held Vibration Meter
Description
Woodlyn, PA: Hand-held meter provides periodic routine vibration checks of machinery and finds general field use where portability and ease of use are required. The Model VM-300 operates from a precision piezoelectric accelerometer and incorporates a charge amplifier input stage for stability and minimizing errors. It can be powered from an internal battery or an external ac adapter. Columbia Research Laboratories, Inc. (800) 813-8471
