Squirrel 450/850 Series Data Logger
Sensors for the 450 Series Squirrel
Sensors providing the industry standard 4-20mA output are accommodated enabling many parameters to be logged, for example, Meteorological sensors (anemometer, rain precipitation, barometric pressure). See the Models tab for more information.

The memory can be expanded to 2M readings (about 2,080,000).
Don't forget that a lot of memory takes time to download and that it is possible to reduce the amount of memory used for a logging run. Eltek loggers download at 38400 baud, and in practice this is about 500 readings per second.
