The Grant sq16 system is a multifunctional, multichannel recording product with long battery life, making it ideal for portable and routine data logging applications such as temperature profiling indoors spaces including data centres
The Grant sq16 is an entry level logger with long battery life, making it ideal for portable and routine data logging applications. The logger can be started or stopped using the multi function button which displays logger status, this means a PC is not required to run the logger in situ. You can store up to 200 million readings in the Squirrel’s onboard memory and up to 6 logger configurations. Use the SD Card memory slot for grabbing measured data in the field or use the SquirrelView app or software to download and export your data.
The sq16plus boasts more advanced technology, giving faster logging speeds. With 3 and 4 wire PT resistance probe support, you get the best accuracy in temperature measurement.

Differential or single ended inputs?
All Grant Squirrel data loggers come with a range of channel options, e.g. 8 to 16 inputs. This refers to their ability to accept either single ended or true differential signals.
Single-ended inputs – each input signal has two connection wires. One is connected to a common terminal on the logger (see diagram). This increases the number of inputs possible to the logger, but results in all the connected sensors having an input at a common potential. However, unlike many loggers, the Grant Squirrel allow these common terminals to be at different potentials (on separate connector blocks), optimising the overall system accuracy.
Differential inputs – each input signal has two connection wires and the logger measures the difference between them. One wire goes to a positive input and one to a negative input (see diagram). In this case none of the inputs needs to be at the same potential as any of the others.
