ECS-1812 is for laboratory use to calibrate vibration transducers which are working during low frequency range. The essential part of ECS-1812 Is a standard shaker with very low working frequency. This standard shaker is built with air bearing guidance with extreme low friction. Working with an innovative active feed-forward control technique, ECS-1812 has excellent performances in low frequency calibration.

The calibration method of ECS-1812 is also the secondary calibration (back to back), to measure the sensitivity of the sensor-under-test (SUT) by point to point swept sine or random vibration over standard or user-defined frequency and acceleration ranges.

ECS-1812 is suitable for calibration of those sensors used for earthquake monitoring, MEMS products development, and industries of railway, oil & gas, electricity, etc.
