The W8-R100D40 is a shock recorder with a high performance piezoresistive 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, with its wide measurement range of 100g is very popular for shock testing. 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.
