ACR - Model OWL Series -Single-Channel Range Settable Data Loggers
The OWL series of data loggers are single-channel, configurable data loggers featuring 10-year battery life, memory capacity of 32,767 readings, optical data transfer, and flashing visual alarm. It is important to note that on competitive products if the replaceable battery comes loose or dies you will not get data - lost time and effort far outweighs any price difference. The OWL Data Logger uses high ratio data compression to backup information up to 128x faster than the connection speed. This means that the data download rate is over 150k readings per second on the LiteLink interface for a value that did not change. Mearsurements are taken every 8 seconds and averaged over sample period for quanitative results. Software Packages are purchased separately as they can support more than one device.
