The UltraShock-EB is a stand alone, battery operated, temperature, humidity, pressure and 3-axis shock data recorder. Continuously sampling at 500Hz, the shock sensors record time and date stamped peak acceleration data at the user-defined intervals that temperature, humidity and pressure readings are stored. Shock data may be displayed for the three axis as well as a calculated vector sum to provide overall acceleration/shock information, along with the temperature, humidity and pressure data. MadgeTech software also provides a summary of statistics for average, minimum and maximum values for all of the sensors. Available in three ranges (±5g, ±50g, ±100g), with extended battery life.Channels: Shock (3 axes), Temperature,Humidity, Pressure Range: Shock: ±5 ±50 ±100 ±250; -20~+60°C; 0~95%RH; 0~30 PSIA Resolution: Shock: ±5: 0.01 ±50: 0.05 ±100: 0.1 ±250: 0.2; 0.1°C; 0.5%RH; 0.002 PSIA Calibrated Accuracy: Shock: ±5: ±0.2 ±50: ±1 ±100: ±2 ±250: ±4; ±0.5°C; ±3%RH; ±1%FSR@25°C Memory: 174,762/channel Sample Rate: 64Hz to 5 minutes for shock, selectable in software.
