SQ2010

A powerful portable data logger for everyday use

The Squirrel 2010 is a versatile, general purpose logger, with 4 to 8 analogue input channels to measure current, voltage, resistance and temperature, plus 8 digital channels. All can be logged or used as triggers to automatically start or stop logging.

It is a compact, portable logger which is also suitable for bench based and fixed installations. Easily programmed via the four integral push buttons and large graphical display and with a basic accuracy of 0.1%, the Squirrel 2010 is able to fulfil many routine data logging needs, including more demanding applications requiring up to 10 readings per second on one channel.
