The W8-E100D40 is a vibration and shock recorder with a high performance piezoelectric accelerometer, a secondary capacitive accelerometer and other environmental sensors. It uploads directly to the enDAQ cloud over WiFi after completing a recording yet this wireless connectivity can be configured to be off when desired. This model is most popular for general purpose testing because of its wide application range. Its aluminum enclosure improves reliability in harsh environments and widens its frequency response. The W8 offers an impressive 4,000 mAh battery (our largest) to allow for the longest recording times of our sensors.
