GP2 Advanced data logger and controller

The Centerpiece of Advanced Environmental Monitoring Systems

The GP2 Data Logger is the core of a professional measurement system, engineered for reliability and flexibility. It excels in acquiring data from a vast array of sensors—from basic thermistors and analog voltages to complex SDI-12 networks—with microvolt sensitivity and excellent long-term stability. Beyond data collection, the GP2 is an intelligent controller. Its unique Script Editor allows users to create complex conditional operations, such as calculating evapotranspiration (Penman-Monteith), implementing PID control loops for irrigation, or triggering alarms without any traditional programming knowledge. This makes it indispensable for long-term ecological research, precision agriculture, and automated industrial processes.

Engineered for Reliability and Unmatched Ease of Use

Despite its advanced capabilities, the GP2 is remarkably easy to deploy. The intuitive DeltaLINK software features a point-and-click interface for configuration, a built-in sensor library, and a powerful Simulator that lets you test complex logging programs in minutes, simulating years of data. The logger itself is built to last, housed in an IP65 weatherproof case with optional internal battery power, allowing it to operate reliably in harsh, remote locations. With seamless integration into the DeltaLINK-Cloud platform, you can view live data, manage multiple sites, and share results with collaborators from anywhere in the world.

Key Advantages of the GP2 System

• Unmatched Input Flexibility: 12 differential analog channels configurable for voltage, resistance, bridge, and potentiometer sensors, plus 4 digital inputs and support for over 60 SDI-12 sensors on a single bus.
• Advanced Control & Calculation: The integrated Script Editor and unlimited Virtual Channels enable on-board data processing, model implementation, and sophisticated control logic without external computers.
• Professional-Grade Accuracy: Features adaptive auto-ranging, microvolt resolution, and exceptional analog accuracy ensured by high-quality components and design.
• Remote Access & Cloud Connectivity: Cellular modem options and DeltaLINK-Cloud integration provide real-time data viewing, remote management, and collaborative sharing from any device.
• Proven Reliability: IP65 rated, robust construction, and built-in error checking ensure dependable operation in the most challenging field conditions for long-term studies.

Optimal Application and System Integration

The GP2 is designed for system integration. For a basic weather station, connect analog sensors for wind, rain, and temperature. For complex soil science projects, network multiple SDI-12 soil moisture probes (like the WET150). Use the Script Editor to calculate daily ET values and control relay outputs to activate irrigation pumps based on real-time soil moisture thresholds. Power the system with internal batteries, an external solar panel, or mains power. For remote sites, install a cellular modem gateway to transmit data automatically to DeltaLINK-Cloud, enabling continuous monitoring without physical visits. The modular design allows for expansion with additional relay outputs or network cabling to connect multiple GP2 units.
