All-in-one Integrated Data Acquisition Platform
Steelhead is leading the shift to a true Internet of Things (IoT) data acquisition experience that incorporates low-power, all-in-one, and patented technology.
Steelhead is a traditional data logger and provides two-way communications. Simple to set up, collect, manage, and analyze measurement by using the Steelhead mobile app via Bluetooth or Stevens-Connect cloud-based software.
Mix and match third-party sensor brands and types.
Easily configure to any SDI-12, Modbus RTU over RS-485, and/or Pulse sensors.
Access and Control Your Data Anywhere Anytime
The Steelhead has global cellular coverage easy set-up for seamless data links and actions between the remote sites and data management program.
Quickly visualize and transform your data into easy-to-use information.
Simple to set up, collect, manage, and analyze your data. Use the Steelhead mobile app via Bluetooth or Stevens-Connect to get started.
