Grant Instruments Data Logging History

Grant has produced, supplied and delivered data recording equipment since the 1980's. In the early stages, our products came 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 developed and use of portable solid-state data loggers when it launched its first Squirrel data logger. This was one of the first ever portable, microprocessor controlled data loggers in the world.

Today, we have over 80,000 Squirrel loggers sold worldwide – a testament to the demand and reliability of our products.
