Handheld data loggers

The Squirrel SQ2020 data loggers by Grant Instruments now include an intuitive and easy to read graphical LCD screen with clear and simple navigation system, fully configurable via the integrated four button keypad. The loggers can be remotely configured with no need to connect to a PC or Laptop. Logger status, setup or real time graphical data (meter mode) are easily viewed, giving accurate (better than 0.1%) and reliable results within minutes of switching on. The handheld data loggers are designed for mobile data logging applications such as field research and external engineering projects e.g.
environmental projects, service or commissioning systems or processes, in food manufacture and research and in all general engineering and manufacturing production projects. The flexible, multi-purpose loggers have eight differential (or sixteen single ended) analogue input channels to measure current, voltage, resistance and temperature, and eight event inputs. All eight event inputs can either be logged or used as triggers to automatically start or stop logging. The onboard memory can store up to 14 million readings as well as retain up to six separate logger configurations. Memory can be extended by using removable MMC/SD cards. The unit is able to fulfil many data logging needs, including more demanding applications requiring up to 100 readings per second on two channels (model SQ2020 2F8). With multiple high specification 24-bit analogue-to-digital converters to facilitate concurrent sampling, four alarm/relay outputs the data loggers are an out-of-the-box solution for a wide range of data logging applications. The new logger is powered from internal cells or an external power supply connection. The onboard RS232 communications can be connected to a GSM modem and there is a choice between a wireless and an Ethernet port to facilitate system networking and the remote transmission of data. SquirrelView set-up and download software for a PC is provided as part of the system to enable users to export stored data to a chosen PC based application. The Squirrel range is compatible with Grant’s comprehensive range of temperature probes and with commercially available sensors for measuring a variety of physical parameters.
