sq Series Overview
Ultimate data logging experience, instant connectivity
The Squirrel sq range of data loggers and software, offers you the ultimate experience in data logging through powerful performance, connectivity and innovative software. These next generation loggers boast multiple features to meet your business and applications needs.
Choose your parameters, set your goals
The universal channel inputs measure current, voltage, resistance, and a host of parameters that includes; temperature, humidity, pressure, flow, wind speed, and concentration. Digital channels automatically trigger or stop logging. This means you can set the logger to automatically start or stop logging if an event occurs.
Control via your app, get the data you need instantly
Communication through a dedicated mobile app comes as standard via wireless Bluetooth as well as the ability to network data loggers through the all-new communications hub, giving a host of remote operating options together with powerful data capture. Get the right data, alerts and alarms when and where you want them.
Easy to use, simple to set up
Easy to use and easily programmed, using the new SquirrelView software. The all-new Squirrel data loggers give you everything from standalone portable data logging to a fixed on-line monitoring system that measures many parameters, always giving you instant data access.
Extend your channels, stack to save space
Each logger has 8 differential channels and is easy to extend using the new SquirrelView software and sqhub. Multiple loggers may be linked, enabling up to 128 channels of data to be measured and monitored at any one time. Designed for stacking, saving you space and giving you the option to use multi channel logging.
Small in size, big in capability
Tough, technology lead loggers, designed to give fast and accurate data, store it safely and retrieve easily for precise reporting when you need it.
The sq16plus
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.

Game-changing data accuracy, empower your industry
Pharmaceutical, thermal mapping, aerospace, automotive, quality control and compliance monitoring
sqhub
The sqhub is our all-new communications gateway, giving connectivity between loggers and a whole host of networking possibilities. WiFi, Ethernet, Open Thread, Lora and 4G connections means, online data from a network of loggers can be accessed instantly. With alerts, alarms and automated data forwarding, the sqhub makes it simple to access the data you want when you want it. The sqhub gives scalability, putting you in control of multiple data loggers and inputs.
Smart technology, simple to control
Innovative software and hardware solutions designed to help you control your process, your budget and your time.
