Grant Squirrel range of data loggers


The Grant Instruments Squirrel range of data loggers are easy to use, hand held, battery powered data loggers which can also be powered via a standard power socket (110-250 volts).
They set the standard for portable data loggers, with their simplicity of operation, very high accuracy of measurement, universal data inputs which can accept virtually any type of sensor signal and their excellent reliability.
The complete Squirrel range offers from 4 to 32 analogue sensor inputs channels, full Wi-Fi, USB and Ethernet connectivity and come complete with the sophisticated SquirrelView configuration and analysis software.
Data logging is now truly possible - "out-of-the-box".
