The Squirrel 2010 A powerful portable data logger

•Very easy to use
•Flexible with universal inputs
•Modem / Ethernet connectivity
•USB / RS232 connectivity

Overview

The SQ2010 is very easy to use via its intuitive icon driven display. For most applications a PC will not be required to configure it – making it ideal for short projects or out of the office applications.
This rapid set up is achieved via its integral four button operator interface – give accurate, reliable results in minutes. It features a large graphical display, provides 0.1% accuracy and boasts good batter life for unattended logging.

The Squirrel 2010 is a versatile general purpose logger with 4 to 8 analogue input channels to measure current, voltage, resistance and temperature; two pulse count or rate inputs and 8 event inputs. An RS232 port is included, allowing connection to modems and other networking devices.
