Data loggers from Grant Instruments are characterised by their ease of use. They are known for their high accuracy and this makes them very popular in scientific Laboratories.
Grant data loggers are built in the UK by Grant Instruments who have been manufacturing data logging equipment throughout its long history, initially in the form of portable multi-channel chart recorders for recording temperature and humidity, including chart recorders for paint oven profiling and similar data logging applications.
In the early 1980s Grant pioneered the development and use of portable solid-state data loggers when it introduced the Squirrel data logger, one of the first truly portable, microprocessor controlled data loggers in the world. To date, over 30,000 Squirrel loggers have been sold worldwide including the various units supplied by Lontek in Australia.
If you want good accurate data when using thermocouples or other temperature sensors, stick with a Grant data logger!
