Data Logger and Data Acquisition Products
Browse products
Data logger products from Grant Instruments are characterised by
their ease of use, high accuracy of measurement and high quality of
build, leading to high reliability of data and system
longevity.
What is data logging?
As science and technology have developed, so the need for data
collection and analysis has grown. This is fulfilled, at least in
part, by dedicated, microprocessor-driven data loggers.
The modern data logger is typically a hand-held battery-operated
device with a large memory, powered by the latest microprocessor
technology and capable of acquiring, processing, storing and
analysing electrical signals at high speed from a wide range of
sensors - at regular intervals or in response to an event such as a
threshold being crossed or a switch being activated.
The sensors may communicate with the logger through a cable or
wireless link and may sense temperature, humidity, pressure, flow,
wind speed, current, voltage, resistance and a host of other
physical parameters that are important in monitoring and
controlling processes or conducting research.
Data stored by stand-alone data loggers is typically downloaded
into a computer for more detailed analysis and reporting, though
some data loggers have sophisticated on-board processing and
analysis capability and can carry out some control functions such
as activating an alarm or a switch.
The advantage of using a dedicated portable data logger compared
to, say, a PC, is that the logger hardware and software are
specifically designed for stand-alone data logging applications.
This means that it is easy to connect and set up sensors and the
logging system is more rugged and less power hungry, making it
capable of running on batteries for longer periods of time, often
in hostile environments.
The advent of wireless communication and networking means that
it is possible to interrogate a logger remotely which can be
extremely useful for unattended or remote applications.
Data loggers from Grant Instruments
The Squirrel range of data loggers from Grant Instruments are
handheld, battery operated and extremely easy to configure. The
Squirrel data loggers are used to monitor a wide range of physical
parameters including temperature, humidity, voltage, current, and
resistance. They are used in varied applications across research,
quality control, all sectors of the industrial and manufacturing
industries and in many of the leading scientific institutions.
Grant's current portfolio of Squirrel data loggers comprises
dedicated multi-channel temperature loggers and a comprehensive
range of high-precision multi-channel universal data loggers with
increasing numbers of inputs and levels of sophistication.
Data Acquisition History of Grant Instruments
Grant Instruments has produced data recording equipment since
the 1980's; initially in the form of portable multi-channel chart
recorders for recording temperature and humidity, including chart
recorders for paint oven profiling.
By the mid 1980's, Grant pioneered the development and use of
portable solid-state data loggers when it introduced the first
Squirrel data logger. This was one of the very first truly
portable, microprocessor controlled data loggers in the world. To
date, well over 30,000 Squirrel loggers have been sold
worldwide.
Extended Data Acquisition Range
The Squirrel data logger range is complemented by data loggers
from other companies both in and outside the Grant group.
DataTaker, a Grant partner is based in Melbourne, Australia.
They specialises in the design and manufacture of a comprehensive
range of expandable rugged data logging systems for complex
applications. Based on the renowned dataTaker loggers and accepting
all common sensors without the need for extra modules, these rugged
instruments offer systems designers, engineers and scientists an
easily integrated solution using Ethernet, wireless and modem
communication with up to over 300 sensor inputs.
Grant acts as the sole importer and distributor of dataTaker
products into the United Kingdom.

Grant affiliate Eltek Ltd, part owned by Grant Instruments and
also based near Cambridge, specialises in the design and
manufacture of wireless data logging systems based on the Squirrel
data logger. The Eltek GenII radio data logging system enables
sensors to be connected to the Receiver Logger by means of a radio
link, ideal where communications across a river, road or simply a
large site need to be established quickly and effectively. Typical
applications include monitoring of buildings (homes, cold stores,
warehouses, museums, galleries, etc.), ground water monitoring and
'through process' monitoring in food production and paint
finishing.
