The Squirrel 2020 series are high performance universal data loggers packed with powerful features to provide
great flexibility to handle a wide range of routine and demanding applications.
Hand-held and lightweight, the Squirrel 2020 models are easy, fast and convenient to use – either as stand-alone
loggers or as PC-linked data acquisition systems in industrial and scientific research and quality assurance
Twin processors, multiple 24-bit analogue-to-digital converters, up to 16 universal channels and a choice of
communications methods ensure that the Squirrel 2020 series provides state-of-the-art data logging and
communication capability for sophisticated applications needs.
Fully configurable via the integrated keypad » 8 true differential or 16 single ended universal
analogue inputs for voltage, current or resistance
Analogue inputs can be used with thermistors,
thermocouples, 2,3 or 4 wire RTD temperature
sensors and 4-20mA signals
Logging rates of up to 100Hz on up to 2 channels
Ethernet (2F8 only), USB and RS232 communication
Large non-volatile internal memory storage for up to
14 million readings
Removable MMC / SD card
Sensor power and FET outputs for use with external
Clear 128*68 dot graphical LCD display
Ethernet (2F8 only), USB and RS232 serial ports are inbuilt.
This allows simple connection to either a PC based TCP/IP
network, a wireless to PC connection or to a GSM modem for
remote data downloading. This flexibility enables global data
access and retrieval as well as complete system integration of
the SQ2020 series into complex and critical applications.
Getting Started Guide
Multiple configurations stored in the logger
Up to six logger configurations ( channel type, names, logging
speeds, triggers etc.) together with the current configuration
can be held in the logger`s internal memory. Additional
configuration settings can also be loaded from the external
MMC/SD memory card. This allows the operator to quickly
and easily switch between logger configurations without the
need for a PC.
Comprehensive software configuration via SquirrelView
The SquirrelView software (supplied with the SQ2020 series
data loggers) allows logger configuration, data download and
export whilst giving the user full control over SQ2020.
optional SquirrelView Plus gives the used access to many
advanced data analyses and archiving/transfer features.
The SQ2020 series uses multiple analogue and digital
converters that enables true concurrent sampling and logging.
It Allows the user to configure a channel to log at a rate of
100Hz(20Hz on 1F8) whilst retaining different sample speeds
on the other channels.
Ideal for measuring dynamic
parameters that change at different rates such as temperature
