Accelerograph – EchoPro SMA

Strong Motion Accelerograph, all in one sensor and recorder, USB storage


Discontinued – replaced by the Gecko SMA

Perfect for structural health monitoring, the Kelunji EchoPro SMA was our all-in-one strong motion accelerograph combined user-friendliness with the reliability and simplicity of a MEMS accelerometer, available in ±2g, ±5g, and higher full scale ranges. Data storage was as simple as you could get: continuous data is stored on a USB drive in one-minute files, organised into year/month/day/hour folders, easily browsed on any PC. This has been carried over in the Gecko SMA, with an SD card replacing the USB drive.

The optional LCD and keypad on the EchoPro is now standard on the Gecko SMA, and now offers full configuration without a PC. An internal battery is optional on the more sensitive Gecko SMA-HR, and all Gecko models have dual alarm outputs. Ethernet is still available on the Gecko, allowing you to send data files to a remote PC. Data telemetry still allows access to our eqAlert service which sends SMS alerts when the SMA detects abnormal activity.
