The UltraShock is a battery powered, stand alone temperature, pressure, humidity and 3-axis shock recorder. The UltraShock measures and records temperature, pressure and humidity at the selected reading rates, while shock is recorded at the peak acceleration levels over the same interval. The UltraShock is specifically designed for documenting dynamic environments such as moving vehicles, trucks, containers, ships, etc. The device is also valuable in characterizing environments such as production and assembly lines of delicate electronics, IC fabrication, communications and computer components. This compact, portable, easy to use device will measure and record up to 174,762 measurements per channel. The storage medium is nonvolatile solid state memory, providing maximum data security even if the battery becomes discharged. The device can be started and stopped directly from your computer and its small size allows it to fit almost anywhere. The UltraShock makes data retrieval quick and easy. Simply plug it into an empty COM or USB port and our user-friendly software does the rest.
