Data Loggers

Delta-T Devices provides a wide range of research-grade sensors for meteorological, hydrological, and environmental measurement and monitoring.

GP2 Data Logger
- Powerful and rugged field data logger
- 12 differential channels and SDI-12 capable
DL6 Data Logger
- Optimised for use with soil moisture sensors
- 8 channel logger with weatherproof case
GP1 Data Logger
- High accuracy 7 channel data logger
- 600,000 readings

Our Data Logger range includes:

GP2 Data Logger

The GP2 Data Logger and Controller easy to use, versatile, rugged and reliable. It is compatible with most sensor types and is ideal for demanding field work. The GP2 has 12 differential channels, powerful controller functionality and has SDI-12 capability. Sophisticated programs can be easily created via a simple scripting editor.

Data Logger – DL6

The DL6 Data Logger is optimised for use with Delta-T soil moisture sensors. It can log Profile Probes or single point soil moisture sensors (ML3, SM150T). The DL6 can also accept a raingauge and soil temperature probe input.

GP1 Data Logger

The GP1 Data Logger is ideal for logging Delta-T soil moisture sensors: up to 2 ThetaProbes or 4 SM150Ts. The GP1 can also log readings from the WET Sensor, and is compatible with most other analog environmental sensors. Versatile control relay options are another key feature of the GP1 data logger.

DeltaLINK-Cloud – online data sharing and management

DeltaLINK-Cloud is a powerful online service for use with Delta-T data loggers and weather stations. It offers secure cloud-based connectivity, data management, and automatic data retrieval. Users can easily upload, store, view, and share their data.

Connection is made using a Delta-T Devices modem gateway. Reports can contain charts for data from one or more loggers. Charting is customisable and can be saved in report form for future use – which can be shared via a unique system-generated URL link.
