Grant Instruments Data Logging History

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.
