The DL6 Data Logger is a high-accuracy, 8-channel logger specifically optimized for use with Delta-T soil moisture sensors like the Profile Probe (PR2), ThetaProbe (ML3), and SM150T. It is a robust, waterproof (IP67) unit designed for simple, reliable long-term monitoring of soil moisture profiles, temperature, and rainfall. With its straightforward setup and proven durability, the DL6 is an ideal choice for agricultural and environmental research applications.
Dedicated Data Logging for Soil Moisture Studies
The DL6 Data Logger is engineered as the perfect companion for Delta-T's range of soil moisture sensors. Its design philosophy prioritizes simplicity and reliability, making it an excellent tool for researchers and technicians who need to deploy a robust monitoring system with minimal setup complexity. The DL6 is built to withstand harsh outdoor conditions, featuring a waterproof IP67 enclosure that protects it from moisture and dust, ensuring continuous operation in the field.
Streamlined for Profile Probes and More
The DL6 is uniquely suited for soil moisture profiling. It can seamlessly connect to and power a PR2/4 or PR2/6 Profile Probe, recording moisture data at multiple depths simultaneously. Beyond profiling, its versatile inputs allow it to log data from a combination of other sensors, including point-based soil moisture probes like the ML3 and SM150T, a temperature sensor, and a pulse-output rain gauge. This integrated approach provides a comprehensive view of soil water dynamics and environmental conditions.
Reliable Performance for Long-Term Deployment
Designed for unattended operation, the DL6 offers a long battery life of approximately one year under typical use conditions (e.g., hourly readings). Its large, non-volatile memory securely stores up to 16,000 readings, safeguarding your data. Configuration and data retrieval are effortless using the included DeltaLINK-PC software, allowing for quick setup and easy export of data for analysis.
Key Advantages and Benefits
- Optimized for Delta-T Sensors: Pre-configured for easy setup with PR2 Profile Probes, ThetaProbes, and SM150T sensors.
- Robust and Weatherproof: IP67-rated enclosure ensures reliable operation in demanding outdoor environments.
- Integrated Measurement: Logs soil moisture, temperature, and rainfall (via a pulse counter) for a complete environmental picture.
- Long Battery Life: Operates for ~1 year on 6 AA alkaline batteries, minimizing maintenance.
- Simple to Use: Easy configuration with user-friendly DeltaLINK-PC software.
Typical Applications and Usage
The DL6 is perfectly suited for a variety of medium-term monitoring scenarios:
- Agricultural irrigation management and scheduling.
- Research projects monitoring soil moisture profiles in hydrology and environmental science.
- Long-term studies of soil water content and its relationship to climate.
Its straightforward design makes it ideal for situations where reliable, set-and-forget data collection is more critical than complex control functions.
