The Squirrel 2020 Wi-Fi hand held data logger combines high performance and universal inputs with the simplicity
of Wi-Fi networking in a compact and easy-to-use instrument.
Using high accuracy, 24-bit analogue to digital converters, removable memory and wireless Ethernet (Wi-Fi)
networking, the SQ2020 Wi-Fi is the ideal data logger for industrial, scientific research and quality assurance
applications.
Together with our comprehensive suite of software, SquirrelView, the SQ2020 provides standalone data acquisition,
simple Wi-Fi networking, real-time metering and data analyses straight out-of-the-box.

Data Sheet
Getting Started Guide
|
Communications - Wi-Fi, 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 2F8 into complex and critical applications.
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.
Software configuration via SquirrelView - The SquirrelView software (supplied with the SQ2020 Wi-Fi
data logger) allows logger configuration, data download and
export whilst giving the user full control over SQ2020. The
optional SquirrelView Plus gives the used access to many
advanced data analyses and archiving/transfer features. Refer
to SquirrelView data sheet for specifications.
Concurrent sampling - The SQ2020 2F8 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 whilst retaining different sample speeds on the other
channels. Ideal for measuring dynamic parameters that
change at different rates such as temperature and pressure.
