SQ2020 Data Loggers

SQ2020 Data Loggers

The Grant Squirrel 2020 series of portable data loggers are high performance, packed with powerful features and universal inputs to provide great flexibility to handle a wide range of routine and demanding applications Hand-held and lightweight, the SQ2020 models are easy, fast and convenient to use. High accuracy 24-bit analog to digital converters, removable memory and ethernet networking (on the 2F8) make the SQ2020 series perfect for industrial, scientific research and quality assurance applications.


SQ2040 Data Loggers

SQ2040 Data Loggers

The Squirrel 2040 series provide high performance universal data loggers packed with the same powerful features as the Squirrel 2020 series with additional high speed logging on up to four channels and twice as many universal input channels. This provides great flexibility to handle a wide range of complex and demanding multi-channel applications such as high-speed vehicle testing or engine monitoring.


Squirrel Temperature Data Loggers

Squirrel Temperature Data Loggers

These systems include temperature data loggers and thermal barriers that are designed to be passed through conveyor or batch ovens. They can measure the temperature profile of items as they pass through the oven to determine how fast they heat/cool or how uniform the temperature is across the part. They are useful for electric, gas and radiant ovens.


YoYo Data Loggers

YoYo Data Loggers

Yoyo data loggers are small but robust and can be used to measure and record a wide variety of variables: temperature, humidity, condensation, extra-low voltage, strain guage, voltage, current, pulse, barometric pressure, as well as light and radiation.
