Description
The SQ Series (SQ16, SQ16 Plus, and SQ16 Pro) represents a next-generation paradigm in high-precision, standalone multichannel industrial data acquisition systems. Engineered with a true 32-bit resolution core architecture, the series features universal isolated inputs capable of concurrently monitoring voltage, process current loops, resistance, and complex thermal properties across 8 differential or 16 single-ended channels without cross-channel signal degradation. Built to support modern flexible field networks, the system operates entirely without legacy physical screens, deploying wireless smartphone app telemetry or desktop SquirrelView interfaces for localised interaction. By linking seamlessly with the modular SQ HUB gateway, the infrastructure expands to support real-time data aggregation across WiFi, Ethernet, LoRa, OpenThread, and 4G LTE pathways, providing robust analytical tracking for electric vehicle testing, cold chain validation, environmental research, and automated SCADA industrial monitoring.

Squirrel Software
The all-new SquirrelView software allows you to easily program the Squirrel SQ Series data loggers. Everything from standalone portable data logging, to a fixed online monitoring system measuring a host of parameters, with instant data access. SquirrelView software allows you to set up the logger and start recording in just a few clicks. Whatever your level of data logging experience, set up simple or advanced acquisitions, record, view and analyse your data quickly and easily.
SQ Hub
The SQ Hub is a communications gateway, giving connectivity between loggers and a whole host of networking possibilities. WiFi, Ethernet, Open Thread, Lora and 4G connections allowing online data from a network of loggers can be accessed instantly. With alerts, alarms and automated data forwarding. The SQ Hub gives scalability and control of multiple data loggers and inputs.
