Overview

Enclosed in a rugged yellow case the size of a lunchbox, the High Speed Data Logger with precision time-stamping, provides precise synchronization of data at remote locations. Sampling rates as high as 10,000 samples per second, provide researchers with a precise GPS timestamp for every measurement taken, and it records information conveniently to a USB jump drive. The device is affordable enough that if lava consumed it, a scientist¹s entire project budget wouldn¹t go with it.

"They don¹t use a lot of battery power, and they¹ve got them set up where I can use a cheap memory stick (for recording data),"... "And there¹s so much memory, I can take measurements 100 times a second if I wanted."

Geophysical Institute Assistant Research Professor Chris Larsen, has purchased five Chaparral Field Data Loggers and will use them to gather seismic data on glaciers to see what sort of signals the glaciers make as they grind away bedrock. Larsen will also use one of the data loggers to gather wave-pressure information that will tell him how frequently icebergs calve from certain glaciers. "They don¹t use a lot of battery power, and they¹ve got them set up where I can use a cheap memory stick (for recording data)", says Larsen. "And there¹s so much memory, I can take measurements 100 times a second if I wanted."

Feature rich and elegant in operation, the all-weather High Speed Data Logger from Chaparral will get the job done for you. Order yours today!
