A powerful portable data logger for everyday use
The Squirrel 2010 is a versatile, general purpose logger, with 4 to 8 analogue input channels to measure current, voltage, resistance and temperature, plus 8 digital channels. All can be logged or used as triggers to automatically start or stop logging.
It is a compact, portable logger which is also suitable for bench based and fixed installations. Easily programmed via the four integral push buttons and large graphical display and with a basic accuracy of 0.1%, the Squirrel 2010 is able to fulfil many routine data logging needs, including more demanding applications requiring up to 10 readings per second on one channel.

Thermal barriers are insulated containers designed to keep heat out so that the Squirrel data logger inside remains at a safe operation temperature for a specified duration. Grant offers a wide range of thermal barriers with different time/temperature specifications.
- Provides protection to Squirrel data loggers when used in high temperature oven profiling applications (static or conveyor)
- A range of standard and customised models with different performance characteristics
- Made from stainless steel, for years of use
- Barriers available for very high temperature applications – manufactured to order
- Suitable for applications in food, powder coating, stove enamelling, ceramic, kiln and furnace
- Can be constructed using special phase change material for added protection for very high temperature applications.
Customised barriers
Thermal Barriers are available in standard sizes or can be customised to suit your specific requirements.
For customised barriers we require details of your application, oven aperture size and expected worst case temperature profile.
