Techni Measure has introduced a new portable handheld shaker designed for the simple testing of accelerometers and vibration monitoring systems to ensure that they are operating correctly.

The shaker is a small, self-contained handheld device which provides a known, controlled RMS or peak vibrating force which is applied to the accelerometer to verify its performance.

The shaker is mechanically attached to the accelerometer and provides a 1g acceleration for multiple calibration cycles at a frequency of 159.2 Hz.

with an automatic shut-off after a 1.5 minute cycle.

For continuous testing, the shut-off control can be overridden.

Accelerometers weighing up to 210 grams can be driven and a mechanical stop on the internal suspension system provides overload protection.

Operating with four AA batteries or an optional AC adaptor, the shaker has a battery life of up to 40 hours and comes with an assortment of accessories including a carrying case, several mounting studs, a battery pack and a storage case.
